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.
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).
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
You can easily use [theme](https://umijs.org/config/#theme) field in [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 [Umi](http://umijs.org/), which could be a object or a javascript file path.
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.
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.
See an example of usage with gulp and [postcss-prefixwrap](https://github.com/dbtedman/postcss-prefixwrap) : https://gist.github.com/sbusch/a90eafaf5a5b61c6d6172da6ff76ddaa
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`.
