Asset Bundles ¶

Bootstrap is a complex front-end solution, which includes CSS, JavaScript, fonts and so on. In order to allow you the most flexible control over Bootstrap components, this extension provides several asset bundles. They are:

• BootstrapAsset - contains only the main CSS files.
• BootstrapPluginAsset - depends on yii\bootstrap\BootstrapAsset, contains the javascript files.
• BootstrapThemeAsset - depends on yii\bootstrap\BootstrapAsset, contains the Bootstrap default theme CSS.

Particular application needs may require different bundle (or bundle combination) usage. If you need only CSS styles, yii\bootstrap\BootstrapAsset will be enough for you. However, if you want to use Bootstrap JavaScript, you need to register yii\bootstrap\BootstrapPluginAsset.

Tip: most of the widgets register yii\bootstrap\BootstrapPluginAsset automatically.
