title: Fixed modal with z-index issue
body: <p>I've got a fixed modal with <code>z-index: 100</code>, but it's not above the all elements on the page. It's bellow an element with <code>position: relative; z-index: 2;</code> and I don't know why?! Here's the <a href="http://jsfiddle.net/xojLzpdy/12/" rel="nofollow noreferrer">fiddle</a>. Any help would be appreciated. Thanks!</p>
