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](https://getbootstrap.com/docs/). Still Yii provides a convenient way to include Bootstrap assets in your pages with a line(s) added to `@app/assets/AppAsset.php`(basic application): ```php public $depends = [ <...> yii\bootstrap5\BootstrapAsset::class, // optional, Bootstrap icons // yii\bootstrap5\BootstrapIconAsset::class ]; ``` Using Bootstrap through Yii asset manager allows you to minimize its resources and combine with your own resources when needed.
