Change style of pseudo elements in angular2
<p>Is it possible to change style of pseudo elements using <code>[style]</code> or <code>[ngStyle]</code> in angular2?</p>

<p>in order to get a blur effect on a div acts like an overlay, and I should set up background-image on pseudo element.</p>

<p>I tried something like </p>

<pre><code>&lt;div class="blur" [style.before.backgroundImage]="'url('+ featuredImage[i] + ' )'"&gt;
</code></pre>

<p>it didn't work. I also tried this</p>

<pre><code>&lt;div class="blur" [ngStyle]="'{:before{ background-image:url('+ featuredImage[i] + ' )}}'"&gt;
</code></pre>
