Ant Design allows you to customize some basic design aspects 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, .85);              // heading text color
@text-color: rgba(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, .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',
+       },
+       javascriptEnabled: true,
+     },
    }],
    // ...other rules
  }],
  // ...other config
}
```

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

### Customize in roadhug or Umi

You can easily use `theme` field in `.webpackrc` file of your project root directory if you are using 如果你在使用 [roadhug](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/3c2a056ef0dac06ce3b4389192691bb1f5c448e2/.webpackrc.js#L19):

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

### Customize in create-react-app

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

## 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`.
- When using `dva-cli@0.7.0+`, you should add the `theme` block to [.roadhogrc](https://github.com/dvajs/dva-example-user-dashboard/commit/d6da33b3a6e18eb7f003752a4b00b5a660747c31) instead of `package.json`.

If you want to override `@icon-url`, the value must be contained in quotes like `"@icon-url": "'your-icon-font-path'"` ([A fix sample](https://github.com/visvadw/dvajs-user-dashboard/pull/2)).
