Ant Design allows 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.

## Less variables

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

- [Default Variables](https://github.com/ant-design/ant-design/blob/master/components/style/themes/default.less)

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

## How to do it

We recommend [modifyVars](http://lesscss.org/usage/#using-less-in-the-browser-modify-variables) to override the default values of the variables. There are two ways to achieve it in practice.

You can use this [example](https://github.com/ant-design/antd-init/tree/master/examples/customize-antd-theme) as a playground.

### 1) Using `theme` property (recommended way)

Specify the `theme` property in `package.json` or `.roadhogrc` file, whose value can be either an object or the path to a JS file that contains the custom values of specific variables:
- example of directly specifying the custom values as an object:
```js
"theme": {
  "primary-color": "#1DA57A",
},
```
- example of specifying a [file path](https://github.com/ant-design/antd-init/blob/master/examples/customize-antd-theme/theme.js) to a JS file:
```js
"theme": "./theme.js",
```

This approach is available only when using [antd-init](https://github.com/ant-design/antd-init) or [dva-cli](https://github.com/dvajs/dva-cli). If you choose other boilerplates, you can write webpack config about [less-loader modifyVars](https://github.com/webpack/less-loader#less-options) like [atool-build ](https://github.com/ant-tool/atool-build/blob/a4b3e3eec4ffc09b0e2352d7f9d279c4c28fdb99/src/getWebpackCommonConfig.js#L131-L138) does.

Note:

- Importing style from less files is necessary.
  - 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 importing 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 quotes must be contained in value like `"@icon-url": "'your-icon-font-path'"` ([A fix sample](https://github.com/visvadw/dvajs-user-dashboard/pull/2)).

### 2) Overriding Less variables (alternative way)

Override variables via less definition files.

Create a standalone less file like the one below, and import it in your project.

   ```css
   @import "~antd/dist/antd.less";   // import official less entry file
   @import "your-theme-file.less";   // override variables here
   ```

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