# A Directory to All You Need to Know About Material UI

## Introduction

The use of UI libraries to set up and build beautiful, slick, and exquisite [user interfaces (UIs)](https://www.interaction-design.org/literature/topics/ui-design) faster has risen over the years with developers relying heavily on these UI libraries to build the entire UI of their software applications and websites. It is even considered undisputable that [every development team needs a UI library](https://medium.com/codex/every-app-development-team-needs-a-ui-library-to-deliver-faster-b1a77c23ff8f).

Almost all major tech companies have their UI library from [Material-UI created by Google](https://m2.material.io/design/introduction) to [Ant Design created by Chinese conglomerate Alibaba](https://ant.design/), to Twitter's [Bootstrap](https://getbootstrap.com/docs/4.0/about/history/), to [visx](https://airbnb.io/visx/) created by Airbnb, to [Fluent](https://www.microsoft.com/design/fluent/) (initially called Fabric React) developed by [Microsoft](https://www.microsoft.com/en-ng/), to [Headless UI](https://headlessui.com/) created by Tailwind Labs. The list goes on.

It might not be worth it to build your entire UI library from scratch by trying to reinvent the wheel, except if you have all the resources at your disposal. You will learn everything about Material UI as a library, from its overview to its principles. You will read about the different UI components such as buttons, cards, lists, etc. You will also learn about the features of Material UI and how to set it up in a project. You will also learn about the reasons for using it to build your applications.

[Material UI is reportedly the #1 UI component library](https://kinsta.com/blog/react-components-library/#top-23-react-ui-component-libraries-for-2023) that offers a set of UI tools to create and deploy new features at speed making it a popular choice among developers.

## What is Material UI?

[Material UI](https://mui.com/) is a popular open-source [ReactJS](https://reactjs.org/) design system library for building user interfaces with a consistent, intuitive, and visually appealing look and feel. It is based on the principles of [Google Material Design](https://m2.material.io/), which aims to provide a unified experience across various platforms and devices. To learn more about the principle of Google's Material Design principles, please read [here](https://m2.material.io/design/introduction#principles).

It is a comprehensive and [well-documented](https://mui.com/material-ui/getting-started/overview/) library of pre-designed and pre-coded [components](https://mui.com/material-ui/getting-started/supported-components/). These components can be easily integrated into your web or mobile app. It provides a wide range of customizable elements, including buttons, input fields, navigation bars, and more, that can be easily styled to match your brand and design requirements.

## Key Features of Material UI

**Flexibility**: One of the key features of Material UI is its flexibility and customization options. You can choose from a wide range of pre-designed components, or you can create your custom elements using the library's theming and styling tools. The library also provides support for responsive design, allowing your interfaces to adapt to different screen sizes and devices.

**Accessibility**: Another notable feature of Material UI is its attention to accessibility. The library follows the Web Content Accessibility Guidelines (WCAG) and provides features such as high contrast mode, keyboard navigation, and screen reader support.

**Seamless customization**: MUI provides robust and versatile components that give you seamless control over the appearance and style of your project.

**Effortlessly implement dark mode**: Dark mode is an important feature for modern websites and mobile apps, as it helps to reduce strain on the eyes and makes it easier to use the app at night. Material UI makes it easy to implement dark mode, as it includes two pre-designed palettes for light and dark themes. To switch to the dark theme, you simply need to set the `type` to `dark` in the palette object when creating a new theme:

```javascript
const darkTheme = createMuiTheme({
  palette: {
    type: 'dark',
  },
});
```

**Time-saving**: Instead of building your UI elements from scratch, you can use the ready-made components in Material UI to quickly and easily put together a user interface. By using Material UI, you can focus more on the functionality of your ReactJS app or website, rather than spending time on the visual design and implementation of UI elements. Ultimately, Material UI is a valuable tool that can help developers save time and streamline their work.

## Getting Started with Material UI

To get started with Material UI in your [ReactJS project](https://create-react-app.dev/), you will need to install the [library](https://www.npmjs.com/package/material-ui) using a package manager such as [npm](https://www.npmjs.com/) or [yarn](https://yarnpkg.com/).

Run the following commands to install the Material UI library:

With NPM

```bash
npm install @mui/material @emotion/react @emotion/styled
```

Or run the following command with Yarn

```bash
yarn add @mui/material @emotion/react @emotion/styled
```

You can then import the components you need into your project and start using them in your code like so:

```javascript
import { Button } from '@material-ui/core'; // Imports Material UI button component

...
```

The library also provides a set of guidelines and best practices for using the components effectively, such as proper use of typography and color, and considerations for mobile and accessibility.

## Components of [Material UI](https://mui.com/)

Material UI provides a variety of pre-designed, customizable components that can be easily integrated into a React web or mobile app. This section will provide a detailed overview of some of the key components offered by [Material UI](https://mui.com/).

### Material UI Buttons

Material UI provides a variety of button styles and options, including raised buttons, flat buttons, and icon buttons.

The Material UI Button component is a versatile and customizable button that can be used in various parts of a user interface. It comes in several styles, such as `contained`, `outlined`, and `text`, and can be customized with options such as color, size, and shape.

```javascript
import { Button } from '@material-ui/core';

function MyButton() {
  return (
    <Button variant="contained" color="primary">
      Click me!
    </Button>
  );
}
```

![Button](https://i.imgur.com/r0yMRg2.png)

This example creates a contained button with the primary color. The variant and color props can be changed to customize the appearance of the button. For example, this creates a small, outlined button with a secondary color, you can use the following code:

```javascript
import { Button } from '@material-ui/core';

function MyButton() {
  return (
    <Button variant="outlined" color="secondary" size="small">
      Click me!
    </Button>
  );
}

```

![Button](https://i.imgur.com/hxM8ZKO.png)

### Material UI Dialog

The Material UI `Dialog` component is a [modal](https://www.copycat.dev/blog/material-ui-modal/) window that displays content and actions on top of the main content of a user interface. It can be used to display a wide range of content, such as forms, text, images, and buttons, and can be customized with options such as layout, color, and shape.

```javascript
import { Dialog, DialogTitle, DialogContent, DialogContentText, DialogActions, Button } from '@material-ui/core';

function MyDialog() {
  const [isOpen, setIsOpen] = useState(false);

  const handleOpen = () => {
    setIsOpen(true);
  };

  const handleClose = () => {
    setIsOpen(false);
  };

  return (
    <>
      <Button variant="outlined" onClick={handleOpen}>
        Open Dialog
      </Button>
      <Dialog open={isOpen} onClose={handleClose}>
        <DialogTitle>Hello, World!</DialogTitle>
        <DialogContent>
          <DialogContentText>
            This is a simple dialog with some text and a button.
          </DialogContentText>
        </DialogContent>
        <DialogActions>
          <Button onClick={handleClose} color="primary">
            Close
          </Button>
        </DialogActions>
      </Dialog>
    </>
  );
}

```

This example creates a button that opens a dialog with a title, some text, and a close button. The `Dialog` component can be customized with various options such as the layout, and color, and this example creates a button that opens a dialog with a title, some text, and a close button.

      label="Name"
      placeholder="Enter your name"
      error={false}
      helperText=""
    />
  );
}
```

This example creates an outlined input field with a label and placeholder text. The variant, label, and placeholder props can be changed to customize the appearance and functionality of the input field.

![input field](https://i.imgur.com/zLBw4sq.png)

For example, this creates a filled input field with an error message, you can use the following code:

```javascript
import { TextField } from '@material-ui/core';

function MyInputField() {
  return (
    <TextField
      variant="filled"
      label="Email"
      placeholder="Enter your email"
      error
      helperText="Invalid email address"
    />
  );
}
```

![Button with error](https://i.imgur.com/QmMeQAm.png)

### Material UI Navigation

The `Navigation` component is a group of components that help you create navigation menus and structures in your user interfaces. It includes components such as the `App Bar`, `Drawer`, and `Tabs`, which can be used to create various types of navigation layouts.

```javascript
import { AppBar, Toolbar, IconButton, Drawer, List, ListItem, ListItemIcon, ListItemText } from '@material-ui/core';
import MenuIcon from '@material-ui/icons/Menu';
import InboxIcon from '@material-ui/icons/Inbox';
import MailIcon from '@material-ui/icons/Mail';

function MyNavigation() {
  const [isDrawerOpen, setIsDrawerOpen] = useState(false);

  const toggleDrawer = (open) => (event) => {
    if (event.type === 'keydown' && (event.key === 'Tab' || event.key === 'Shift')) {
      return;
    }

    setIsDrawerOpen(open);
  };

  const menuList = (
    <div onClick={toggleDrawer(false)} onKeyDown={toggleDrawer(false)}>
      <List>
        <ListItem button>
          <ListItemIcon>
            <InboxIcon />
          </ListItemIcon>
          <ListItemText primary="Inbox" />
        </ListItem>
        <ListItem button>
          <ListItemIcon>
            <MailIcon />
          </ListItemIcon>
          <ListItemText primary="Mail" />
        </ListItem>
      </List>
    </div>
  );

  return (
    <>
      <AppBar position="static">
        <Toolbar>
          <IconButton edge="start" color="inherit" aria-label="menu" onClick={toggleDrawer(true)}>
            <MenuIcon />
          </IconButton>
        </Toolbar>
      </AppBar>
      <Drawer open={isDrawerOpen} onClose={toggleDrawer(false)}>
        {menuList}
      </Drawer>
    </>
  );
}
```

![MUI - Navigation](https://i.imgur.com/bpXFCpz.gif)

### Material UI Cards

The `Card` component is a container that displays content and actions in a visually appealing way. It can be used to display a wide range of content, such as text, images, lists, and buttons, and can be customized with options such as layout, color, and shape.

```javascript
import { Card, CardContent, CardActions, Typography, Button } from '@material-ui/core';

function MyCard() {
  return (
    <Card>
      <CardContent>
        <Typography variant="h5" component="h2">
          Hello, World!
        </Typography>
        <Typography color="textSecondary">
          This is a simple card with some text and a button.
        </Typography>
      </CardContent>
      <CardActions>
        <Button size="small">Learn More</Button>
      </CardActions>
    </Card>
  );
}
```

The `typography` system is based on a set of pre-defined type styles, ranging from headings and subheadings to body text and captions. These styles are designed to be used in combination with Material UI's layout and spacing utilities to create visually cohesive and easy-to-read interface designs. In addition to the standard type styles, Material UI also includes several utility classes for fine-tuning the appearance of text, such as font-weight, color, and text alignment.

### Material UI Table

The `Table` component is a data table that displays a structured set of data in a [grid](https://www.copycat.dev/blog/material-ui-textfield/) of rows and columns. It can be used to display a wide range of data, such as lists, tables, and grids, and can be customized with options such as layout, color, and sorting.

```javascript
import { Table, TableBody, TableCell, TableHead, TableRow, Paper } from '@material-ui/core';

function MyTable() {
  const rows = [
    { id: 1, name: 'John', age: 30 },
    { id: 2, name: 'Jane', age: 25 },
    { id: 3, name: 'Bob', age: 35 },
  ];

  return (
    <Paper>
      <Table>
        <TableHead>
          <TableRow>
            <TableCell>ID</TableCell>
            <TableCell>Name</TableCell>
            <TableCell>Age</TableCell>
          </TableRow>
        </TableHead>
        <TableBody>
          {rows.map((row) => (
            <TableRow key={row.id}>
              <TableCell>{row.id}</TableCell>
              <TableCell>{row.name}</TableCell>
              <TableCell>{row.age}</TableCell>
            </TableRow>
          ))}
        </TableBody>
      </Table>
    </Paper>
  );
}
```

![Table](https://i.imgur.com/hAcQs5y.png)

### Material UI Text Field

The `Text Field` component is a form control that allows users to input text in a user interface. It can be used to input a wide range of data, such as names, emails, passwords, and numbers, and can be customized with options such as layout, color, and validation.

```javascript
import { TextField } from '@material-ui/core';

function MyTextField() {
  const [value, setValue] = useState('');

  const handleChange = (event) => {
    setValue(event.target.value);
  };

  return (
    <TextField
      label="Enter your name"
      value={value}
      onChange={handleChange}
    />
  );
}

```

This example creates a text field with a label and allows the user to input text. The Text Field component can be customized with various options such as the layout, color, and validation.

Overall, the Text Field component is a useful tool for allowing users to input text in a user interface. Check out his article on **Material UI Table**: [Material UI Table: A Detailed Guide For Making a Great Table](https://www.copycat.dev/blog/material-ui-table/)

### Material UI Select

The `Select` component in Material UI is a form control that allows users to select a value from a list of options. It is a versatile component that can be used in a variety of contexts, such as in forms, filters, and [dropdown menus](https://www.copycat.dev/blog/material-ui-select/).

To use a Select component in your project, you will first need to install Material UI and import the Select component.

Here is an example of how to use a Select component in a React component:

```javascript
import React, { useState } from 'react';
import { Select, MenuItem } from '@material-ui/core';

export const App = () => {
  const [value, setValue] = useState('');
  const handleChange = event => {
    setValue(event.target.value);
  };

  return (
    <Select value={value} onChange={handleChange}>
      <MenuItem value='option1'>Option 1</MenuItem>
      <MenuItem value='option2'>Option 2</MenuItem>
      <MenuItem value='option3'>Option 3</MenuItem>
    </Select>
  );
};

```

This example creates a Select component with three options, each with a value and a label. The component uses a state variable to store the selected option and a change handler to update the state when the user selects a new option.

![Select](https://i.imgur.com/Jb0VaVS.gif)

## Material UI Icons

Material UI Icons are a comprehensive set of scalable vector icons that can be easily customized and integrated into any web or mobile app. The icons follow the guidelines of Google's Material design principles, which aims to provide a unified experience across various platforms and devices.

To use these icons in your project, you will first need to install the library using a package manager such as npm or yarn. You can then import the icons you need into your project and use them in your code.

```javascript
import { Icon } from '@material-ui/core';

function MyComponent() {
  return (
    <Icon fontSize="large">favorite</Icon>
  );
}
```

This example creates an icon component with the "favorite" icon, which is displayed in large size.

You can customize the appearance and behavior of the Icon component using props such as `fontSize`, `color`, and `edge`. You can also use the `component` prop to use the `Icon` as a custom component, such as a Link or a Button. It is recommended [not to use MUI icons without understanding these things](https://www.copycat.dev/blog/material-ui-icons/).

## Material UI Modal

A `Modal` is a component in Material UI that allows you to display a dialog or overlay on top of the current page. Modals are commonly used to display additional content or prompts, such as [forms](https://www.copycat.dev/blog/material-ui-form/), confirmation dialogs, and notifications.

To use a Modal in your project, you will first need to install Material UI and import the Modal and Button components.

Here is an example of how to use a Modal in a React component:

```javascript
import { Modal, Button } from '@material-ui/core';

function MyComponent() {
  const [open, setOpen] = useState(false);

  const handleOpen = () => {
    setOpen(true);
  };

  const handleClose = () => {
    setOpen(false);
  };

  return (
    <div>
      <Button variant="contained" onClick={handleOpen}>
        Open Modal
      </Button>
      <Modal
        open={open}
        onClose={handleClose}
      >
        <div style={{ width: '400px', height: '200px', backgroundColor: 'white' }}>
          This is the content of the Modal.
        </div>
      </Modal>
    </div>
  );
}

```

This example creates a Modal that is displayed when the user clicks the "Open Modal" button. The Modal has a white background and contains some content. For in-depth knowledge on using Material UI `Button`, check out the [complete guide to using the Material UI button in React](https://www.copycat.dev/blog/material-ui-button/)

You can customize the appearance and behavior of the Modal using props such as `open`, `onClose`, `disableBackdropClick`, and `disableEscapeKeyDown`. You can also use the `PaperProps` prop to customize the container of the Modal, such as its size and style.

Here is an example of a Modal with customized size and style:

```javascript

import { Modal, Button, Paper } from '@material-ui/core';

function MyComponent() {
  const [open, setOpen] = useState(false);

  const handleOpen = () => {
    setOpen(true);
  };

  const handleClose = () => {
    setOpen(false);
  };

  return (
    <div>
      <Button variant="contained" onClick={handleOpen}>
        Open Modal
      </Button>
      <Modal
        open={open}
        onClose={handleClose}
      >
        <Paper style={{ width: '800px', height: '400px', backgroundColor: '#F5F5F5', padding: '20px' }}>
          This is the content of the Modal.
        </Paper>
      </Modal>
    </div>
  );
}

```

![Modal](https://i.imgur.com/GuTwWch.gif)

This example creates a Modal with a Paper container that has a custom size, style, and padding.

Modals are a useful component in Material UI that can help you display additional content or prompts in an overlay on the current page. With a wide range of customization options, you can create Modals that match your design requirements and enhance the user experience of your app.

## Material UI Colors

One of the key features of Material design principles is its extensive color system, which allows developers to easily incorporate a wide range of colors into their projects.

The Material UI colors are divided into two main categories: primary and secondary colors.

* **Primary colors** are used for the main elements in the UI, such as the app bar, buttons, and text fields. Material UI provides the following primary colors:
  * `primary.main`: The main primary color of your application.
  * `primary.light`: A lighter variant of the primary color.
  * `primary.dark`: A darker variant of the primary color.
* **Secondary colors** are used for secondary elements in the UI, such as error messages, icons, and helper text. Material UI provides the following secondary colors:
  * `secondary.main`: The main secondary color of your application.
  * `secondary.light`: A lighter variant of the secondary color.
  * `secondary.dark`: A darker variant of the secondary color.

Here's an example of how to use the Material UI colors to change the background color of a component:

```javascript
import { makeStyles } from '@material-ui/core/styles';

const useStyles = makeStyles((theme) => ({
  root: {
    backgroundColor: theme.palette.primary.main,
  },
}));

export default function ColorExample() {
  const classes = useStyles();
  return <div className={classes.root}>This has a primary color background</div>;
}

```

The `makeStyles` hook is used to create a style object that sets the background color of the component to the primary color in the Material UI color palette. The `theme.palette` object contains the different color palettes available in Material UI. The `main` property is used to reference the main color of the palette.

You can also use the `secondary` property to reference the secondary color of the palette, or you can use the `error` property to reference the error color of the palette.

You can also use the `background` and `color` utility classes to set the background and text color of an element respectively:

```javascript
import { makeStyles } from '@material-ui/core/styles';
import clsx from 'clsx';

const useStyles = makeStyles((theme) => ({
  root: {
    backgroundColor: theme.palette.background.paper,
    color: theme.palette.text.primary,
  },
}));

export default function ColorExample() {
  const classes = useStyles();
  return <div className={clsx(classes.root, 'bg-primary', 'text-secondary')}>This has a primary color background and secondary color text</div>;
}
```

![MUI - Colors](https://i.imgur.com/MgWRdB7.png)

The `clsx` function is used to combine the classes from the useStyles hook and the background-primary and text-secondary classes.

You can use predefined colors to create a consistent and visually pleasing color scheme for your application. The Material Design color system provides a set of primary and secondary colors that are designed to work together to create harmonious color combinations.

## Material UI Tabs

The `Tabs` component is used for creating tabbed navigation in your web app. This renders a set of tabs and their associated content, allowing the user to switch between different sections of content.

```javascript
import React from 'react';
import { Tabs, Tab } from '@material-ui/core';

function Example() {
  const [value, setValue] = React.useState(0);

  const handleChange = (event, newValue) => {
    setValue(newValue);
  };

  return (
  <>
    <Tabs value={value} onChange={handleChange}>
      <Tab label='Tab 1' />
      <Tab label='Tab 2' />
      <Tab label='Tab 3' />
    </Tabs>
    <div>
      {value === 0 && <div>Content of tab 1</div>}
      {value === 1 && <div>Content of tab 2</div>}
      {value === 2 && <div>Content of tab 3</div>}
    </div>
  </>
  );
}
```

You can see how to define a value and handle change events for the tabs, by doing this the value state will change each time the user changes tabs. Also, you can render different content for each tab by checking the value state, this way when the user changes tabs, the content will change as well.

The `Tab` component, which is a child of the `Tabs` component, is used to define the tabs themselves. The `label` prop is used to define the text that will be displayed on the tab button.

You can also use `indicatorColor` and `textColor` props in the `Tabs` component to change the color of the underline that appears under the selected tab and the text color of the tabs.

Additionally, you can use the `scrollButtons` prop to enable scrolling in case you have too many tabs to fit on the screen.

```javascript
<Tabs
  scrollButtons="on"
  indicatorColor="primary"
  textColor="primary"
>

```

## Material UI Form

Material UI comes with a set of pre-built form components that makes it easy to create consistent, visually pleasing forms in your application.

Here's an example of a simple form created with Material UI:

```javascript
import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import TextField from '@material-ui/core/TextField';
import Button from '@material-ui/core/Button';

const useStyles = makeStyles((theme) => ({
  root: {
    '& > *': {
      margin: theme.spacing(1),
      width: '25ch',
    },
  },
}));

export default function SimpleForm() {
  const classes = useStyles();
  const [values, setValues] = React.useState({
    firstName: '',
    lastName: '',
  });

  const handleChange = (event) => {
    setValues({
      ...values,
      [event.target.name]: event.target.value,
    });
  };

  const handleSubmit = (event) => {
    event.preventDefault();
    console.log(values);
  };

  return (
    <form className={classes.root} onSubmit={handleSubmit}>
      <TextField
        label="First Name"
        name="firstName"
        value={values.firstName}
        onChange={handleChange}
      />
      <TextField
        label="Last Name"
        name="lastName"
        value={values.lastName}
        onChange={handleChange}
      />
      <Button type="submit" color="primary">
        Submit
      </Button>
    </form>
  );
}
```

This form has two text fields for the user to enter their first and last name, and a submit button. The form uses the `TextField` component from Material UI for the input fields and the `Button` component for the submit button. The `handleChange` function updates the form's state when the user types in the input fields, and the `handleSubmit` function logs the form values to the console when the user submits the form.

Also, if you want to validate the form and show error messages, you can use the `error` and `helperText` props provided by the `TextField` component.

Also, if you want to validate the form and show error messages, you can use the error and helperText props provided by the TextField component.

```javascript
import React from 'react';
import { useForm } from 'react-hook-form';
import { TextField } from '@material-ui/core';

export default function FormWithValidation() {
  const { register, handleSubmit, errors } = useForm();

  const onSubmit = (data) => {
    console.log(data);
  };

  return (
   <form onSubmit={handleSubmit(onSubmit)}>
      <TextField
        name='firstName'
        label='First Name'
        inputRef={register({ required: true })}
        error={Boolean(errors.firstName)}
        helperText={errors.firstName && 'This field is required'}
      />
    </form>
  )
};
```

## Material UI Box

Material UI's Box component is a simple container component that provides flexible layout options. It can be used to create a container for other components, apply spacing and alignment, and control the dimensions of the container.

Here's an example of how to use the Box component:

```javascript
import React from 'react';
import { Box } from '@material-ui/core';

export default function MyComponent() {
  return (
    <Box p={2}>
      <p>This is some content inside a box.</p>
    </Box>
  );
}
```

![Cards](https://i.imgur.com/UxFcPej.png)

The Box component is used as a container for a paragraph of text. The `p` prop is used to apply padding of 2 units to the container. Material UI uses a spacing scale of 8 units, so 2 units of padding is equivalent to 16 pixels.

You can also use Box to align the content inside it, for example:

```javascript
<Box display="flex" alignItems="center" justifyContent="center" p={2}>
      <p>This is some content inside a box.</p>
</Box>

```

Here, the `display` prop is set to "flex" to enable flexbox layout for the container. The `alignItems` prop is set to "center" to center the content vertically within the container, and the `justifyContent` prop is set to "center" to center the content horizontally.

You can also use Box to define the width and height of the container, for example:

```javascript
  <Box width={1/2} height={250} p={2}>
    <p>This is some content inside a box.</p>
  </Box>

```

Here, the `width` prop is set to 1/2 to make the container take up half of the available width, and the `height` prop is set to 250 pixels to set the container to a specific height.

In addition to the above example, you can also use Box as a responsive layout using the `display` prop and the `width`, `height`, `minWidth`, and `maxWidth` props.

As you can see, the [Box component](https://www.copycat.dev/blog/material-ui-box/) is a powerful and flexible layout tool that can be used to create a wide variety of layouts in your Material UI application.

## Material UI Navbar

Material UI's AppBar component can be used as a navigation bar, also known as a navbar, at the top of your application. It provides a consistent visual style and layout and can be customized with various props.

Here's an example of how to create a simple navbar with a title and a menu button:

```javascript
import React from 'react';
import { AppBar, Toolbar, Typography, IconButton } from '@material-ui/core';
import MenuIcon from '@material-ui/icons/Menu';

export default function Navbar() {
  return (
    <AppBar position="static">
      <Toolbar>
        <IconButton edge="start" color="inherit" aria-label="menu">
          <MenuIcon />
        </IconButton>
        <Typography variant="h6">
          My App
        </Typography>
      </Toolbar>
    </AppBar>
  );
}
```

![navbar](https://i.imgur.com/i3QkCg7.png)

`AppBar` is used to create the navbar container, the `Toolbar` component is used to create a container for the navbar content, the `IconButton` component is used to create a button with a menu icon, and the `Typography` component is used to create a title for the navbar.

The `position` prop of the `AppBar` is set to "static" to make the navbar stay at the top of the screen when the user scrolls the page.

Also, you can add more functionality like adding a menu or links to navigate through the pages, for example:

```javascript
import React from 'react';
import { Link } from 'react-router-dom'
import { AppBar, Toolbar, Typography, IconButton, makeStyles, Button } from '@material-ui/core';
import MenuIcon from '@material-ui/icons/Menu';

const useStyles = makeStyles((theme) => ({
  root: {
    flexGrow: 1,
  },
  menuButton: {
    marginRight: theme.spacing(2),
  },
  title: {
    flexGrow: 1,
  },
}));

export default function Navbar() {
  const classes = useStyles();
  return (
    <AppBar position="static">
      <Toolbar>
        <IconButton edge="start" className={classes.menuButton} color="inherit" aria-label="menu">
          <MenuIcon />
        </IconButton>
        <Typography variant="h6" className={classes.title}>
          My App
        </Typography>
        <Button color="inherit" component={Link} to='/home'>Home</Button>
        <Button color="inherit" component={Link} to='/about'>About</Button>
      </Toolbar>
    </AppBar>
  );
}
```

The `Button` component is used to create a link to navigate to a specific page, and the `Link` component from `react-router-dom` is used to link the button to the specific route.

You can use Material UI's AppBar component to create a simple and customizable navbar for your application with the ability to add more functionality and flexibility.

## Material UI Core

Material UI Core is a set of pre-built components that implement the Material Design guidelines from Google. It provides a wide variety of components that can be used to create a consistent, visually pleasing user interface for your application.

Here's an example of how to use some of the Material UI Core components to create a simple card:

```javascript
import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Card from '@material-ui/core/Card';
import CardContent from '@material-ui/core/CardContent';
import Typography from '@material-ui/core/Typography';

const useStyles = makeStyles({
  root: {
    minWidth: 275,
  },
  bullet: {
    display: 'inline-block',
    margin: '0 2px',
    transform: 'scale(0.8)',
  },
  title: {
    fontSize: 14,
  },
  pos: {
    marginBottom: 12,
  },
});

export default function SimpleCard() {
  const classes = useStyles();

  return (
    <Card className={classes.root}>
      <CardContent>
        <Typography variant="h5" component="h2">
          My Card
        </Typography>
        <Typography className={classes.pos} color="textSecondary">
          A simple card
        </Typography>
        <Typography variant="body2" component="p">
          Lorem ipsum dolor sit amet, consectetur adipiscing elit.
          Praesent eget risus vitae massa semper aliquam quis mattis quam.
        </Typography>
      </CardContent>
    </Card>
  );
}
```

![MUI - cards](https://i.imgur.com/FgkWF3g.png)

In this Material UI Core example, the `Card` component is used to create the card container, the `CardContent` component is used to create a container for the card content, and the `Typography` component is used to create the title, subtitle, and body of the card. We have demystified everything you need to know about the Material UI Card component in this post on [Guide to Creating Cards with Material UI Card](https://www.copycat.dev/blog/material-ui-card/).

You can also use other Material UI Core components such as `Button`, `TextField`, `FormControl`, `Select`, `Switch`, `Checkbox`, `Radio`, `Slider`, `Chip`, `Badge`, `Avatar` and many more.

## Material UI Responsiveness

Material UI provides a set of utilities that allow you to create responsive designs that adapt to different screen sizes and orientations. You can use these utilities to change the layout, spacing, and visibility of your components based on the size of the screen.

One of the most useful utilities provided by Material UI for creating responsive designs is the `useMediaQuery` hook. This hook allows you to create responsive designs by conditionally rendering components based on the screen size.

Here's an example of how to use the `useMediaQuery` hook to create a responsive design:

```javascript
import { useMediaQuery } from '@material-ui/core';

export default function ResponsiveContainer() {
  const matches = useMediaQuery('(min-width:600px)');

  return (
    <div>
      {matches ? (
        <LargeScreenContent />
      ) : (
        <SmallScreenContent />
      )}
    </div>
  );
}
```

The `useMediaQuery` hook is used to check if
the screen width is at least 600 pixels. If the screen width is greater than or equal to 600 pixels, the `LargeScreenContent` component is rendered. If the screen width is less than 600 pixels, the `SmallScreenContent` component is rendered.
