jQuery - Supersleight & filter through background-image properties
<p>I want to apply Supersleight to my transparent png images on my site, so far I only apply it to images with a PNG image in the <code>src</code> attribute.</p>

<p>Now I want to filter through all elements with a <code>background-image</code> property which contains '.png'.</p>

<p>Can someone please suggest a query?</p>

<p>Thanks in advance.</p>
