postcss配置

# postcss-config-ivan

## 是否px转换为rem

  在项目中package.json文件中的congfig.ispxtorem(Boolean)属性决定是否转换

## postcss在webpack中配置

  先安装必备包

  ```sh
  npm install --save-dev postcss-config-ivan
  ```

  在webpack3.0配置添加在modules.rules下：

  ```js

  {
          test: /\.(css|scss)$/,
          use: ExtractTextPlugin.extract({
            fallback: require.resolve('style-loader'),
            use: [{
              loader: require.resolve('css-loader'),
              options: {
                importLoaders: 1,
                sourceMap: true,
              },
            },
            // 实际配置-begin
            {
              loader: require.resolve('postcss-loader'),
              options: {
                ident: 'postcss',
                config: {
                  path: require.resolve('postcss-config-ivan'),
                },
                sourceMap: true,
              },
            },
            // 实际配置-end
            require.resolve('resolve-url-loader'),
            {
              loader: require.resolve('sass-loader'),
              options: {
                sourceMap: true,
              },
            },
            ],
          }),
        },
        // 文
  ```
