Ant Design allows you to customize our design tokens in order to meet the needs of UI diversity from business and brand, including primary color, border radius, border color, etc.

## Ant Design Less variables

We are using [Less](http://lesscss.org/) as the development language for styling. A set of less variables are defined for each design aspect that can be customized to your needs.

There are some major variables below, all less variables could be found in [Default Variables](https://github.com/ant-design/ant-design/blob/master/components/style/themes/default.less).

```less
@primary-color: #1890ff; // primary color for all components
@link-color: #1890ff; // link color
@success-color: #52c41a; // success state color
@warning-color: #faad14; // warning state color
@error-color: #f5222d; // error state color
@font-size-base: 14px; // major text font size
@heading-color: rgba(0, 0, 0, 0.85); // heading text color
@text-color: rgba(0, 0, 0, 0.65); // major text color
@text-color-secondary : rgba(0, 0, 0, .45); // secondary text color
@disabled-color : rgba(0, 0, 0, .25); // disable state color
@border-radius-base: 4px; // major border radius
@border-color-base: #d9d9d9; // major border color
@box-shadow-base: 0 2px 8px rgba(0, 0, 0, 0.15); // major shadow for layers
```

Please report an issue if the existing list of variables is not enough for you.

## How to do it

We will use [modifyVars](http://lesscss.org/usage/#using-less-in-the-browser-modify-variables) provided by less.js to override the default values of the variables, You can use this [example](https://github.com/ant-design/create-react-app-antd) as a live playground. We now introduce some popular way to do it depends on different workflow.

### Customize in webpack

We take a typical `webpack.config.js` file as example to customize it's [less-loader](https://github.com/webpack-contrib/less-loader) options.

```diff
// webpack.config.js
module.exports = {
  rules: [{
    test: /\.less$/,
    use: [{
      loader: 'style-loader',
    }, {
      loader: 'css-loader', // translates CSS into CommonJS
    }, {
      loader: 'less-loader', // compiles Less to CSS
+     options: {
+       modifyVars: {
+         'primary-color': '#1DA57A',
+         'link-color': '#1DA57A',
+         'border-radius-base': '2px',
+         // or
+         'hack': `true; @import "your-less-file-path.less";`, // Override with less file
+       },
+       javascriptEnabled: true,
+     },
    }],
    // ...other rules
  }],
  // ...other config
}
```

Note that do not exclude antd package in node_modules when using less-loader.

### Customize in roadhog or Umi

You can easily use `theme` field in [.webpackrc](https://github.com/ant-design/ant-design-pro/blob/b7e7983661eb5e53dc807452e9653e93e74276d4/.webpackrc.js#L18) (roadhog) or [config/config.js](https://github.com/ant-design/ant-design-pro/blob/56e648ec14bdb9f6724169fd64830447e224ccb1/config/config.js#L45) (Umi) file of your project root directory if you are using [roadhog](https://github.com/sorrycc/roadhog) or [Umi](http://umijs.org/), which could be a object or a javascript file path.

```js
"theme": {
  "primary-color": "#1DA57A",
},
```

Or just [a javascript file path](https://github.com/ant-design/ant-design-pro/blob/b7e7983661eb5e53dc807452e9653e93e74276d4/.webpackrc.js#L18):

```js
"theme": "./theme.js",
```

### Customize in create-react-app

Follow [Use in create-react-app](/docs/react/use-with-create-react-app).

### Customize in less file

Another approach to customize theme is creating a `less` file within variables to override `antd.less`.

```css
@import '~antd/dist/antd.less'; // Import Ant Design styles by less entry
@import 'your-theme-file.less'; // variables to override above
```

Note: This way will load the styles of all components, regardless of your demand, which cause `style` option of `babel-plugin-import` not working.

## How to avoid modifying global styles?

Currently ant-design is designed as a whole experience and modify global styles (eg `body` etc). If you need to integrate ant-design as a part of an existing website, it's likely you want to prevent ant-design to override global styles.

While there's no canonical way to do it, you can take one of the following paths :

### Configure webpack to load an alternate less file and scope global styles

It's possible to configure webpack to load an alternate less file:

```ts
new webpack.NormalModuleReplacementPlugin( /node_modules\/antd\/lib\/style\/index\.less/, path.resolve(rootDir, 'src/myStylesReplacement.less') )

#antd { @import '~antd/lib/style/core/index.less'; @import '~antd/lib/style/themes/default.less'; }
```

Where the src/myStylesReplacement.less file loads the same files as the index.less file, but loads them within the scope of a top-level selector : the result is that all of the "global" styles are being applied with the #antd scope.

### Use a postcss processor to scope all styles

See an example of usage with gulp and [postcss-prefixwrap](https://github.com/dbtedman/postcss-prefixwrap) : https://gist.github.com/sbusch/a90eafaf5a5b61c6d6172da6ff76ddaa

## Not working?

You must import styles as less format. A common mistake would be importing multiple copied of styles that some of them are css format to override the less styles.

- If you import styles by specifying the `style` option of [babel-plugin-import](https://github.com/ant-design/babel-plugin-import), change it from `'css'` to `true`, which will import the `less` version of antd.
- If you import styles from `'antd/dist/antd.css'`, change it to `antd/dist/antd.less`.
