Bootstrap widgets
=================

Yii includes support for the [Bootstrap 3](http://getbootstrap.com/) markup and components framework out of the box. Bootstrap is an excellent, responsive framework that can greatly speed up your development process.

The core of Bootstrap is represented by two parts:

- CSS basics, such as grid layout system, typography, helper classes, and responsive utilities.
- Ready to use components, such as menus, pagination, modal boxes, tabs etc.

Basics
------

Yii doesn't wrap 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](http://getbootstrap.com/css/). Still Yii provides a
convenient way to include bootstrap assets in your pages with a single line added to `AppAsset.php` located in your
`config` directory:

```php
public $depends = array(
	'yii\web\YiiAsset',
	'yii\bootstrap\BootstrapAsset', // this line
	// 'yii\bootstrap\BootstrapThemeAsset' // uncomment to apply bootstrap 2 style to bootstrap 3
);
```

Using bootstrap through Yii asset manager allows you to minimize its resources and combine with your own resources when
needed.

Yii widgets
-----------

Most complex bootstrap components are wrapped into Yii widgets to allow more robust syntax and integrate with
framework features. All widgets belong to `\yii\bootstrap` namespace:

- Alert
- Button
- ButtonDropdown
- ButtonGroup
- Carousel
- Collapse
- Dropdown
- Modal
- Nav
- NavBar
- Progress
- Tabs
