title: how to enlarge a div on hover without moving other div
body: <p>I'm looking to achieve a hover effect like <a href="http://shopper.queldorei.com/index.php/women/dresses.html" rel="nofollow">this hover</a> where the image enlarges but does not displace the surrounding divs.  I have seen this done by assigning relative and absolute positioning and a z-index but that isn't working for me.  Perhaps I assigned those values to the wrong classes.  My code is below...any help is appreciated</p>
  
  <p>I wasn't totally sure how to post the code here so...my site (and code problem) can be viewed <a href="http://4ucaps.activo.com/fitted/mlb/?dir=desc&amp;order=position" rel="nofollow">here</a></p>
  
  <p>It's my first time posting here.  Thanks for the instruction.  Here is the code...</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div class="products-container"&gt;
     &lt;div class="products-container-inner"&gt;
        &lt;div class="item"&gt;
        &lt;div class="item"&gt;
        &lt;div class="item"&gt;
        &lt;div class="item"&gt;
  </code></pre>
