When you first started learning how to code, one of the most common clichés you heard was, “Don’t reinvent the wheel.” This is the same case in web development, and there’s no need to start from scratch every time you build a website or web application.

Web applications are the gateway to success for your product or service, and in today’s digital era, providing a seamless user experience is crucial. Users expect your web application to load quickly and have a visually appealing user interface. According to Taylor & Francis Online, the average users form an opinion of a business/product within 0.05 seconds of viewing the website. A good user interface layout, design, and web experience are essential.

JavaScript has become an integral part of every aspect of web development, powering the dynamic and interactive experiences that users expect. Regarding building complex and interactive user interfaces, React, a JavaScript library, has become one of the most popular and widely used JavaScript libraries.

With over 19.5 million weekly downloads, React has proven a reliable and efficient tool for building complex and interactive user interfaces.

### Quick Recap of React

[React](https://www.lambdatest.com/blog/react-testing-tutorial/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog) is a popular open-source front-end JavaScript library that can be used to build user interfaces (UIs). Facebook developed it and has gained popularity for its efficient and reusable components.

React allows developers to build complex UIs by breaking them down into smaller, reusable components. These components can be used across different parts of an application, which reduces the amount of code that needs to be written and maintained.

React uses a declarative approach to programming, meaning developers only need to describe what they want the UI to look like, and React takes care of the underlying logic to make it happen. React also has a virtual [DOM](https://www.lambdatest.com/blog/document-object-model/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog), which helps to improve performance by only updating the parts of the UI that have changed rather than the entire UI.

According to the State of JS Survey 2022, React is the most popular frontend library, with approximately 17.4 million weekly downloads. It is widely used in the industry and has been adopted by many Fortune 500 companies, including Facebook, Instagram, Airbnb, Netflix, and Dropbox.

[*Source*](https://2022.stateofjs.com/en-US/libraries/rendering-frameworks/)

With its plethora of libraries, components, and extensions, it provides a complete and extensive solution for developing React-based web applications. The component-based architecture of React lets developers break up a user interface into smaller, reusable parts. This makes it easier to build and maintain large applications.

React can create various applications, including web, mobile, and desktop applications. It is often used with other libraries and frameworks like Redux, React Native, and [Next.js](https://www.lambdatest.com/blog/nextjs-testing/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog).

Many production-grade frameworks, such as Next, are built on React. These frameworks help to extend the capabilities of React and provide additional features and functionality that can make building web applications more accessible and more efficient.

### What are React-based CSS Frameworks and Component Libraries?

CSS frameworks for React and Component libraries are the foundations of React-based applications. They provide pre-built user interface components that can be easily integrated into the application, saving developers time and effort in creating these components from scratch.

Both the React UI framework and a component library provide UI components, but they differ in their scope and level of customization.

Some best CSS frameworks for React include Material-UI, React Bootstrap, Semantic UI React, Ant Design, Blueprint, and many more. These frameworks provide a wide range of customizable, pre-built UI components and libraries that can be used to build beautiful and responsive user interfaces.

Here are some differences between CSS frameworks for React and their component libraries based on some key factors:

**Scope**

CSS frameworks for React offer a set of ready-made UI components, such as navigation menus, layouts, responsive templates, and more, which are integral to building modern-day websites. With the help of these best CSS frameworks for React, front-end developers can save time and effort by using pre-built components already optimized for performance and accessibility while still being customizable to suit their needs. Some popular UI frameworks include Material UI, Ant design, etc.

On the other hand, React component libraries are more specific; they provide individual, reusable components, such as buttons, inputs, and icons, that can be combined and customized to create more complex UIs. Some of the popular component libraries include React Bootstrap, Chakra UI, etc.

**Adaptability**

CSS frameworks for React are less customizable and have several restrictions, limiting the developer’s ability to create a unique UI design. This set of best CSS frameworks for React has its design patterns and rules that must be followed to keep the application consistent.

On the other hand, React component libraries are more developer friendly and customizable compared to UI frameworks. Unlike UI frameworks, we can easily customize the designs that match the design of your project, and you don’t need to override the styles used in UI frameworks.

**Learning Curve**

CSS frameworks for React are difficult to grasp because they have design patterns, constraints, and conventions that must be followed to ensure consistency throughout the application. But once you become familiar with this set of best CSS frameworks for React, it is just a piece of cake 🙂

On the other hand, React component libraries are generally considered easier to use than CSS frameworks for React, as they often have a lower learning curve. Component libraries do not require you to follow a specific set of design patterns and conventions, which gives you greater flexibility and control over the design and functionality of your UI.

**Accessibility**

CSS frameworks for React and component libraries can help make your application more accessible to all users. Many of these libraries already include accessibility features, so you don’t have to worry about adding them yourself. This means that people with special abilities can still easily use your application.

On the other hand, choosing between various lists of best CSS frameworks for React and component libraries depends on what you need for your project and what you prefer. If you want a lot of pre-made components and a consistent UI design, go for a framework. But if you want more control and customization options, go for a component library.

In the next section, we’ll look at some best CSS frameworks for React you can use in web designs.

### Choosing the Right CSS Framework for React-Based Applications

We have gone through a long list of the 23 best CSS frameworks for React. Each year, there are new additions to the list, making it even harder to choose the right one.

When picking the right CSS framework for React-based applications, it’s important to consider your project’s needs. It is important to note that installing a heavy package for simple UI elements can increase loading time and slow down your application. In this section of the blog on the best CSS frameworks for React, we will look into some of the aspects you must consider while picking the best CSS frameworks for React and a component library for your testing needs.

### Cross Browser Compatibility

[Cross browser compatibility](https://www.lambdatest.com/learning-hub/cross-browser-compatibility?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=learning_hub) is an important factor when choosing the best CSS frameworks for React among the various options available. Some new UI libraries focus on the more recent versions of React, and they might need to be compatible with older versions. It can be a challenging time for developers who will use those libraries.

Some [React UI component libraries](https://www.lambdatest.com/blog/best-react-component-libraries-2021/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog) may not be compatible with all major browsers and devices, which can result in issues with the user experience and functionality of your web application. For instance, if a UI library heavily relies on CSS, there is a probability that the CSS properties are specific to certain platforms and may not function as intended.

One way you can verify and test compatibility is to check if the library supports major browsers and devices using a cloud-based digital experience testing platform like LambdaTest that provides comprehensive [cross browser testing](https://www.lambdatest.com/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=webpage) capabilities.

LambdaTest is a cloud-based unified intelligent [digital experience testing](https://www.lambdatest.com/blog/digital-experience-testing-guide/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog) platform that allows developers and testers to perform manual and automated testing over a wide range of browsers and real devices. Additionally, LambdaTest also offers a wide range of integrations with popular [automation testing frameworks](https://www.lambdatest.com/blog/automation-testing-frameworks/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog) like [Selenium](https://www.lambdatest.com/selenium?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=webpage), [Appium](https://www.lambdatest.com/appium-mobile-testing?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=webpage), and [Playwright](https://www.lambdatest.com/playwright?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=webpage), allowing you to [test React applications](https://www.lambdatest.com/blog/react-testing-tutorial/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog) into your existing testing workflow seamlessly.

### Documentation

UI libraries like Material UI have gained significant popularity, and one of the reasons for this is their well-documented API and usage examples. Proper documentation not only helps developers understand how to use the library effectively, but it also helps them to debug and fix issues.

One noticeable feature of popular libraries like Material UI is the overall flow of the documentation. Material UI’s documentation is well-structured and easy to follow, making it easy to find what you need and get started with the library. Each component is well explained with code as well as a live example.

Most UI libraries try to keep their documentation up-to-date and thorough to ensure that developers have the necessary resources to use their components effectively. From the examples above, it’s clear that developers find it much easier to understand and use the different parts and features of a UI library when the documentation is clear and well-organized.

While evaluating a UI library, look for API references, usage examples, and code snippets that demonstrate how to use the library’s components and features. It is also a good practice to check the GitHub repository and issues section for the UI library you are considering. This can give you a better idea of the development activity and community support for the library.

### Ease of Customization

While choosing the best CSS frameworks for React from the list of the best CSS frameworks, it is important to consider the level of customization it provides. Some libraries may limit the amount of customization possible, while others may offer extensive options for customization.

Most organizations have their own brand colors and aesthetics. When using a UI library, it is important to ensure that it provides the flexibility to customize the look and feel of the UI to match your brand. This includes options for modifying colors, typography, and other styling elements.

The following example shows how we can override the default style and create custom styling of a Material UI button.

```plaintext
import { Button, Typography } from "@mui/material";
import { ThemeProvider } from "@mui/material/styles";
import { createTheme } from "@mui/material/styles";


const theme = createTheme({
  palette: {
    primary: {
      main: "#4cff50",
    },
    secondary: {
      main: "#f50057",
    },
    background: {
      default: "#f5f5f5",
      paper: "#ffffff",
    },
    text: {
      primary: "#333333",
      secondary: "#666666",
    },
  },
});


function App() {
  return (
    <ThemeProvider theme={theme}>
      <div>
        <Typography variant="h4" gutterBottom>
          Material UI Theme
        </Typography>
        <Typography variant="body1" paragraph>
          In this example, we have created a theme with primary and secondary
          colors, a default background color, and some typography styles. We
          have also added a margin to the buttons.
        </Typography>
        <Button variant="contained" color="primary" sx={{ margin: 5 }}>
          Primary Button
        </Button>
        <Button variant="contained" color="secondary" sx={{ margin: 5 }}>
          Secondary Button
        </Button>
      </div>
    </ThemeProvider>
  );
}


export default App;
```

**Output:**

![image](https://cdn-images-1.medium.com/max/800/0*GyFv8LP5SVP638MZ.png)

Also, look for libraries that offer a wide range of pre-built components and the ability to create your custom components easily. One thing to note when using an extensive library is that it can increase the project size and the page load time in slower networks.

### Learning Curve

It’s crucial to think about the learning curve when deciding on a user interface framework or component library. Some libraries, such as Semantic UI React, are more complex and challenging to use. On the other hand, some libraries, like Material UI, are more straightforward and scalable. Material UI has the largest UI community in the React ecosystem. It has been around since 2014, almost as long as React itself.

Search for libraries with thorough documentation, tutorials, and community support to make learning easier. This can help you quickly get up to speed on the library’s features and functionality and provide a valuable resource if you run into any issues or have questions.

### Performance

Performance is considered the key to the success of any web application. A fast and responsive application can provide users with a smooth and seamless experience, making them more likely to engage with your product and return in the future.

When choosing a UI library for your app, it’s important to pay attention to its performance. You want to avoid ending up with a library that slows down your app’s loading time or negatively affects its performance.

![image](https://cdn-images-1.medium.com/max/800/0*pS7YfXK_zFJe-Bnl.png)

It’s a good idea to look for libraries that offer optimization options, such as code splitting and [lazy loading](https://www.lambdatest.com/blog/how-to-lazy-load-images-javascript/?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=blog). These features can help improve your app’s performance by reducing the amount of code that needs to be loaded at once.

### Accessibility

Accessibility is one of the most important aspects of software development. While choosing the best CSS frameworks for React, it’s important to consider accessibility as one of the key factors. An accessible UI library can help you build an inclusive app that everyone, including people with special abilities, can use.

To ensure that your app is fully accessible, you should look for libraries that offer [accessibility testing](https://www.lambdatest.com/learning-hub/accessibility-testing?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=learning_hub) features, such as keyboard navigation and screen reader support. These features can help users with special abilities to navigate and interact with your app more easily.

Also, make sure that the library you chose follows accessibility standards such as WCAG. This can help ensure that your app complies with accessibility laws and regulations. Some libraries, like Semantic UI React, have accessibility issues addressed by the community, which can make UI components hard to use for people with special abilities.

### Material UI vs. Semantic UI: Comparison with LT Browser 2.0

Let’s now look at an example where we try to replicate the same UI using Material UI and Semantic UI and then check the responsiveness score using LT Browser 2.0. We will also look into the performance score.

### Semantic UI React

We will use Semantic UI React to build a registration form component with a few form components like form, checkbox, and button.

Let’s consider taking an example for better understanding.

```plaintext
import React, { useState } from 'react';
import { Container, Form, Checkbox, Button } from 'semantic-ui-react';
import 'semantic-ui-css/semantic.min.css'


function RegistrationForm() {
  const [formData, setFormData] = useState({
    firstName: '',
    lastName: '',
    email: '',
    password: '',
    confirmPassword: '',
    age: '',
    gender: '',
    address: '',
    phoneNumber: '',
    agreeTerms: false,
  });


  const [formErrors, setFormErrors] = useState({});


  const handleInputChange = (event, { name, value, checked }) => {
    setFormData((prevState) => ({
      ...prevState,
      [name]: name === 'agreeTerms' ? checked : value,
    }));
  };


  const handleSubmit = (event) => {
    event.preventDefault();


    // Validate form data
    const errors = {};


    if (!formData.firstName) {
      errors.firstName = 'Please enter your first name';
    }


    if (!formData.lastName) {
      errors.lastName = 'Please enter your last name';
    }


    if (!formData.email) {
      errors.email = 'Please enter your email address';
    } else if (!/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(formData.email)) {
      errors.email = 'Please enter a valid email address';
    }


    if (!formData.password) {
      errors.password = 'Please enter a password';
    } else if (formData.password.length < 6) {
      errors.password = 'Password must be at least 6 characters long';
    }


    if (formData.password !== formData.confirmPassword) {
      errors.confirmPassword = 'Passwords do not match';
    }


    if (!formData.age) {
      errors.age = 'Please enter your age';
    } else if (formData.age < 18) {
      errors.age = 'You must be at least 18 years old to register';
    }


    if (!formData.gender) {
      errors.gender = 'Please select your gender';
    }


    if (!formData.address) {
      errors.address = 'Please enter your address';
    }


    if (!formData.phoneNumber) {
      errors.phoneNumber = 'Please enter your phone number';
    } else if (!/^\d{10}$/.test(formData.phoneNumber)) {
      errors.phoneNumber = 'Please enter a valid phone number';
    }


    if (!formData.agreeTerms) {
      errors.agreeTerms = 'You must agree to the terms and conditions';
    }


    setFormErrors(errors);


    // Submit form data if there are no errors
    if (Object.keys(errors).length === 0) {
      console.log(formData);
    }
  };


  const {
    firstName,
    lastName,
    email,
    password,
    confirmPassword,
    age,
    gender,
    address,
    phoneNumber,
    agreeTerms,
  } = formData;


  return (

### Material UI

Now, we will try replicating the Semantic UI form component into the Material UI component. Note that a replica may only sometimes be possible due to differences in the design systems and available features. However, we aim to create a similar form using Material UI and compare the two in terms of aesthetics and functionality.

Let’s consider taking an example for better understanding.

```plaintext
import React, { useState } from "react";
import {
  Typography,
  Grid,
  Paper,
  TextField,
  Button,
  FormControl,
  FormControlLabel,
  Checkbox,
  FormHelperText,
  Select,
  MenuItem,
  RadioGroup,
  Radio,
  FormLabel,
} from "@mui/material";
import { createTheme, ThemeProvider } from "@mui/material/styles";
import { blue } from "@mui/material/colors";


const theme = createTheme({
  palette: {
    primary: {
      main: blue[500],
    },
  },
});


function RegistrationForm() {
  const [formData, setFormData] = useState({
    firstName: "",
    lastName: "",
    email: "",
    password: "",
    confirmPassword: "",
    age: "",
    gender: "",
    address: "",
    phoneNumber: "",
    agreeTerms: false,
  });


  const [formErrors, setFormErrors] = useState({});


  const handleInputChange = (event) => {
    const { name, value, checked } = event.target;
    setFormData((prevState) => ({
      ...prevState,
      [name]: name === "agreeTerms" ? checked : value,
    }));
  };


  const handleSubmit = (event) => {
    event.preventDefault();


    // Validate form data
    const errors = {};


    if (!formData.firstName) {
      errors.firstName = "Please enter your first name";
    }


    if (!formData.lastName) {
      errors.lastName = "Please enter your last name";
    }


    if (!formData.email) {
      errors.email = "Please enter your email address";
    } else if (!/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(formData.email)) {
      errors.email = "Please enter a valid email address";
    }


    if (!formData.password) {
      errors.password = "Please enter a password";
    } else if (formData.password.length < 6) {

As you can see from the responsiveness and performance report of both Material UI and Semantic UI React in LT Browser 2.0, Material UI is more optimized for responsive web design and performs better than Semantic UI.

With that being said, choose the React UI library that meets all your requirements and is a good fit for the scope of your project. One way to make a more informed decision is to try different libraries and conduct some testing to determine which one best meets your needs. This may involve building prototypes or performing [UI testing](https://www.lambdatest.com/learning-hub/ui-testing?utm_source=devto&utm_medium=organic&utm_campaign=may10_ap&utm_term=ap&utm_content=learning_hub) to see how the different libraries perform.

### Wrapping Up!
