yii2使用vendor文件夹下的的css文件

yii2 使用 vendor 下在css样式, 可以新建一个Asset，定义 public $sourcePath="@vendor/..",如:public $sourcePath = '@vendor/almasaeed2010/adminlte/bower_components/';，

如: 我自己定义的 IoniconsAsset.php

<?php
namespace appassets;

use yiiwebAssetBundle;

class IoniconsAsset extends AssetBundle
{
    public $sourcePath = '@vendor/almasaeed2010/adminlte/bower_components/';

    public $css = [
        // 'css/site.css',
        'Ionicons/css/ionicons.min.css'
    ];
    public $js = [
    ];
    public $depends = [
        'yiiwebYiiAsset',
    ];
}
