+Bootstrap widgets
-=========================
+=================
 
-Overview
+Yii includes support of [Bootstrap 3](http://getbootstrap.com/) markup and components framework out of the box. It is an
---------
+excellent framework that allows you to speed up development a lot.
 
+Bootstrap is generally about two parts:
+
+- Basics such as grid 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
+);
+```
+
+Using bootstrap through Yii asset manager allows you to combine and minimize its resources with your own ones 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. Let's review these.

+View
+====
+
+View is an important part of MVC and is reponsible for how data is presented to the end user.
+
+Basics
+------
+
+Yii uses PHP in view templates by default so in a web application a view typically contains some HTML, `echo`, `foreach`
+and such basic constructs. It may also contain widget calls. Using complex code in views is considered a bad practice.
+Such code should be moved to controller or widgets.
+
+View is typically called from controller action like the following:
+
+```php
+public function actionIndex()
+{
+	return $this->render('index', array(
+		'username' => 'samdark',
+	));
+}
+```
+
+First argument is the view name. In context of the controller Yii will search for its views in `views/site/` where `site`
+is controller ID. For details on how view name is resolved please refer to [yii\base\Controller::render] method.
+Second argument is data array that contains key-value pairs. Value is available in the view as a variable named the same
+as the corresponding key.
+
+So the view for the action above should be in `views/site/index.php` and can be something like:
+
+```php
+<p>Hello, <?php echo $username?>!</p>
+```
+
+Intead of just scalar values you can pass anything else such as arrays or objects.
+
+Layout
+------
+
+Partials
+--------
+
+
+Widgets
+-------
+
+Security
+--------
+
+One of the main security principles is to always escape output. If violated it leads to script execution and,
+most probably, to cross-site scripting known as XSS leading to leaking of admin passwords, making a user to automatically
+perform actions etc.
+
+Yii provides a good toolset in order help you escaping your output. The very basic thing to escape is a text without any
+markup. You can deal with it like the following:
+
+```php
+<?php
+use yii\helpers\Html;
+?>
+
+<div class="username">
+	<?php echo Html::encode($user->name); ?>
+</div>
+```
+
+When you want to render HTML it becomes complex so we're delegating the task to excellent
+[HTMLPurifier](http://htmlpurifier.org/) library. In order to use it you need to modify your `composer.json` first by
+adding the following to `require`:
+
+```javascript
+"ezyang/htmlpurifier": "v4.5.0"
+```
+
+After it's done run `php composer.phar install` and wait till package is downloaded. Now everything is prepared to use
+Yii's HtmlPurifier helper:
+
+```php
+<?php
+use yii\helpers\HtmlPurifier;
+?>
+
+<div class="post">
+	<?php echo HtmlPurifier::process($post->text); ?>
+</div>
+```
+
+Note that besides HTMLPurifier does excellent job making output safe it's not very fast so consider
+[caching result](caching.md).
+
+Alternative template languages
+------------------------------
+
+There are offlicial extensions for [Smarty](http://www.smarty.net/) and [Twig](http://twig.sensiolabs.org/). In order
+to learn more refer to [Using template engines](template.md) section of the guide.
