yii2简单使用less代替css示例

'components' => [  'assetManager' => [    'converter' =>      [        'class' => /singrana/assets/Converter::className(),      ],  ],],

class AppAsset extends AssetBundle{  public $basePath = '@webroot';  public $baseUrl = '@web';  public $css = [    'css/site.less', //*.less代替*.css并在css目录中使用.less后缀的，并在版本库中忽略.css文件  ];  public $js = [  ];  public $depends = [    'yii/web/YiiAsset',    'yii/bootstrap/BootstrapAsset',  ];}
