Basic Usage =========== Yii doesn't wrap the bootstrap basics into PHP code since HTML is very simple by itself in this case. You can find details about using the basics at [bootstrap documentation website](https://getbootstrap.com/docs/). Still Yii provides a convenient way to include bootstrap assets in your pages with a single line added to `AppAsset.php` located in your `@app/assets` directory: ```php public $depends = [ 'yii\web\YiiAsset', 'yii\bootstrap5\BootstrapAsset', // this line ]; ``` Using bootstrap through Yii asset manager allows you to minimize its resources and combine with your own resources when needed.
