title: How do I enable an overlay to pop up on a webpage depending on the item I click?
body: <p>If you go to <a href="http://www.sherwin-williams.com/painting-contractors/project-solutions/residential-repaints/facility-illustration-guides/" rel="nofollow">http://www.sherwin-williams.com/painting-contractors/project-solutions/residential-repaints/facility-illustration-guides/</a> ,you will notice that when you click on the '+' an overlay pops up.  I was curious as to how they were getting this done, so I downloaded the source and decided to play around with it.</p>
  
  <p>I was able to recreate the webpage here (<a href="http://residentialrepaint.com/repaints.php" rel="nofollow">http://residentialrepaint.com/repaints.php</a>), but I noticed the overlays didn't work.  I tried digging through the jquery-ui.min.js file where I think the problem is, but the file is very large and hard to dig through.  I think maybe the file is fine, but there is some linking error.  Does anybody know how to get this working, and where the problem lies so that I can better understand how the overlays are working?</p>
