I have a Bootsrap modal window like this:
<div class="modal slacker-modal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="false">
modal content
</div>
When I open this modal I want to blur (with blur.js) the whole background, which is a slider. Every image on that slider have this class: .vegas-background
When I close the modal window unblur the background image.
