title: How can i use "z-index" as an css attribute selector?
body: <p>I need an attribute selector to match the first div element with an z-index and a value of 0.
  tTis is how i tried to get hands on the element,by using the css attribute selector syntax in jquery: </p>
  
  <pre><code>$("div[z-index='0']").first().doSomeJqueryStuff() ....
  </code></pre>
  
  <p>In my document there is an explicitly set z-index with a value of 0 on a div element, but the selector returns no result.
  Thanks for help!</p>
