<!-- A) Grid Container -->
<div class="rex-grid-container">
  <!-- B) Grid Row -->
  <div class="rex-grid-row">

    <div class="rex-grid-col">Content Left</div>

    <div class="rex-grid-col-10">Content Right</div>

# How to integrate ReX in your project
## A) JavaScript modules

### <img src="https://raw.githubusercontent.com/rakuten-rex/grid/master/project-scripts/webpack/markdown/logos/react.svg?sanitize=true" height="16" /> React component (JavaScript + CSS Styles)

For plug and play components integration.   

Example: 

`my-component.jsx`

```jsx
import { Row, Container, Col } from '@rakuten-rex/grid/Grid';

function MyCustomComponent() {
  return (
    <Container>
      <Row>
        <Col>
        Content Left
        </Col>
        <Col>
        Content Right
        </Col>
      </Row>
    </Container>
  );
}
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/grid/master/project-scripts/webpack/markdown/logos/css-3.svg?sanitize=true" height="16" /> CSS Styles only

For your own JavaScript integration (React, Vue, Angular, etc.) or Static HTML.

#### Using CSS Variables (Modern Websites and WebApps)

Example: 

`my-component.jsx`

```jsx
import '@rakuten-rex/grid/Grid/css';

function MyCustomComponent() {
  return (
    <div class="rex-grid-container">
      <div class="rex-grid-row">
        <div class="rex-grid-col">Content Left</div>
        <div class="rex-grid-col">Content Right</div>
      </div>
    </div>
  );
}
```

#### Using Static CSS (Legacy Websites)

Example: 

`my-component.jsx`

```jsx
import '@rakuten-rex/grid/Grid/css/static';

function MyCustomComponent() {
  return (
    <div class="rex-grid-container">
      <div class="rex-grid-row">
        <div class="rex-grid-col">Content Left</div>
        <div class="rex-grid-col">Content Right</div>
      </div>
    </div>
  );
}
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/grid/master/project-scripts/webpack/markdown/logos/sass.svg?sanitize=true" height="16" /> Sass mixins

For your own customization of styles (React, Vue, Angular, etc.) or Static HTML.

Example: 

`my-styles.scss`

```scss
@import '~@rakuten-rex/grid/Grid/sass/styles.mixin';

// Main local variables
$rex-grid-prefix: 'my-custom-rex-grid';
$rex-grid-gutter-width: 24px !default;
$rex-grid-container-max-widths: (
  xs: 290px,
  sm: 384px,
  md: 696px,
  lg: 936px,
  xl: 1224px
) !default;
$rex-grid-breakpoints: (
  xs: 0,
  sm: 414px,
  md: 768px,
  lg: 1024px,
  xl: 1280px,
  xxl: 1440px
) !default;
$rex-grid-columns: 12 !default;
$rex-grid-row-columns: 6 !default;
$rex-grid-displays: none, inline, inline-block, block, table, table-row, table-cell, flex, inline-flex !default;

// ReX Grid Mixin customizable styles generator
@include rex-grid(
  $rex-grid-prefix, 
  $rex-grid-gutter-width, 
  $rex-grid-container-max-widths, 
  $rex-grid-breakpoints, 
  $rex-grid-columns,
  $rex-grid-row-columns,
  $rex-grid-displays
);
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/grid/master/project-scripts/webpack/markdown/logos/vue.svg?sanitize=true" height="16" /> Vue.js

A basic implementation based on HTML structure and import CSS styles into your component.

Example: 

`my-component.vue`

```vue
<template>
    <div class="rex-grid-container">
      <div class="rex-grid-row">
        <div class="rex-grid-col">Content Left</div>
        <div class="rex-grid-col">Content Right</div>
      </div>
    </div>
</template>
<script>
export default {
  name: 'MyComponent',
}
</script>
<style scoped>
@import "~@rakuten-rex/grid/Grid/css";
</style>
```


## B) Static HTML

Copy-paste the stylesheet `<link>` into your `<head>` tag to load our CSS styles.

### Using CSS Variables (Modern Websites and WebApps)
**Production mode URL** (recommended for Static HTML projects):  
```
https://unpkg.com/@rakuten-rex/grid@1.6.0/Grid/Grid.production.min.css
```


Development mode URL (for local testing):  

```
https://unpkg.com/@rakuten-rex/grid@1.6.0/Grid/Grid.development.css
```


### Using Static CSS (Legacy Websites)

```
https://unpkg.com/@rakuten-rex/grid@1.6.0/Grid/Grid.static.css
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/grid/master/project-scripts/webpack/markdown/logos/html-5.svg?sanitize=true" height="16" /> Single component integration
Add it from unpkg.com CDN (NPM) into your HTML template or HTML static page.

Example: 

`my-page.html`

```html
<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <title>My Page</title>
    <!-- ReX grid -->
    <link href="https://unpkg.com/@rakuten-rex/grid@1.6.0/Grid/Grid.production.min.css" rel="stylesheet">
  </head>
  <body>
    <div class="rex-grid-container">
      <div class="rex-grid-row">
        <div class="rex-grid-col">Content Left</div>
        <div class="rex-grid-col">Content Right</div>
      </div>
    </div>
  </body>
</html>
```
