title: Yii2 autocomplete CSS classes in PhpStorm
body: <p>In my projects I enjoy how PhpStorm can often autocomplete css class names etc, especially when using something like Bootstrap or similar. However, a lot of that seems to be forfeited when doing things inside a framework like Yii2.</p>
  
  <p>For example, if I wanted to do the following, I won't have any autocomplete functionality on the class names.</p>
  
  <pre><code>&lt;?= Html::tag('p', Html::encode($user-&gt;name), ['class' =&gt; 'text-center']) ?&gt;
  </code></pre>
  
  <p>Is there any extra awareness in PhpStorm to get that back? Or just something you have to live without if you want to render certain blocks in an OO way?</p>
