Yii2 introduction of css and js files

There are several ways to introduce:

1, the view may be introduced directly on the page

<?php 
use yii\helpers\Html;
?>
<?=Html::cssFile('@web/css/index.css')?>
<?=Html::jsFile('@web/js/jquery.min.js')?>

2, may be directly introduced into the native code write, project directory path / web / css or / js

<script src="js/nav.js"></script> 

3, you can use assetBundle management style and css js script
resource package definition: basic / assets / AppAsset.php

<?php
/**

 * @copyright Copyright (c) 2008 Yii Software LLC
 * @license http://www.yiiframework.com/license/
 */
 
namespace app\assets;
 
use yii\web\AssetBundle;
 
/**

 */
class AppAsset extends AssetBundle
{
    public $basePath = '@webroot';
    public $baseUrl = '@web';
    public $css = [
        'css/site.css',
        'css/base.css'
    ];
    public $js = [
        'js/sliders.js'
    ];
    public $depends = [ //依赖包，没有可以不写
        'yii\web\YiiAsset',
        'yii\bootstrap\BootstrapAsset',  
    ];
 
    //定义按需加载JS方法，注意加载顺序在最后  
    public static function addScript($view, $jsfile) {  
        $view->registerJsFile($jsfile, [AppAsset::className(), 'depends' => 'api\assets\AppAsset']);  
    }  
      
   //定义按需加载css方法，注意加载顺序在最后  
    public static function addCss($view, $cssfile) {  
        $view->registerCssFile($cssfile, [AppAsset::className(), 'depends' => 'api\assets\AppAsset']);  
    }  
}

At the beginning of the view files are written:

<?php
use yii\helpers\Html;
use app\assets\AppAsset;
 
AppAsset::register($this);
 
?>

Until now, we can test in the browser, we found no introduction css and js files to note here, we also need the final step:
In view of the file we'll add the code (Note: If we use public view file can be added to public view the file, if not used, can be placed in a separate page)

<?php
   $this->beginPage() 
?> 
<?php $this->head() ?>
<?php $this->beginBody() ?> 
<?php $this->endBody() ?>
<?php $this->endPage() ?>

4, the package does not need the resource manager in the methods defined, as long as the page in the view can be directly introduced

AppAsset::register($this);  
//css定义一样  
$this->registerCssFile('@web/css/font-awesome.min.css',['depends'=>['api\assets\AppAsset']]);  
  
 $this->registerJsFile('@web/js/jquery-ui.custom.min.js',['depends'=>['api\assets\AppAsset']]);  
//$this->registerJsFile('@web/js/jquery-ui.custom.min.js',['depends'=>['api\assets\AppAsset'],'position'=>$this::POS_HEAD]);
