    text
    copied!<p>I have a row of 160x160px floated images resized to 100x100px by the browser.</p> <p>On hover, the images animate to their usual size and margins are manipulated to keep them in the same place.</p> <p>What I want to achieve next is to have the enlarged image move to the front, then back again after the hover event. I'm try to achieve this by adding and removing a class where z-index is 100.</p> <p>The HTML is:</p> <pre><code> &lt;div id="content_top"&gt; &lt;img class="thumbnail" src="images/thumbs/thumb1.jpg" width="100" height="100" border="0" alt=""/&gt; &lt;img class="thumbnail" src="images/thumbs/thumb2.jpg" width="100" height="100" border="0" alt=""/&gt; &lt;img class="thumbnail" src="images/thumbs/thumb3.jpg" width="100" height="100" border="0" alt=""/&gt; &lt;img class="thumbnail" src="images/thumbs/thumb4.jpg" width="100" height="100" border="0" alt=""/&gt; &lt;img class="thumbnail" src="images/thumbs/thumb5.jpg" width="100" height="100" border="0" alt=""/&gt; &lt;/div&gt; </code></pre> <p>With the CSS:</p> <pre><code>#content_top { height: 210px; } #content_top img{ float:left; padding: 0 0 0 10px; } .ontop { z-index: 100; } </code></pre> <p>The jQuery I'm using is:</p> <pre><code>$('#content_top img').hover(function(){ $(this).filter(':not(:animated)').animate({ 'width' : '160px', 'height' : '160px', 'marginLeft' : '-30px', 'marginRight' : '-30px', 'marginBottom' : '-30px' }, 'fast', 'linear' ).addClass('ontop'); }, function(){ $(this).animate({ 'width' : '100px', 'height' : '100px', 'marginLeft' : '0px', 'marginRight' : '0px', 'marginBottom' : '0px' }, 'fast', 'linear' ).removeClass('ontop'); }); </code></pre> <p>All works fine, except the z-index part. I've tested that the class is being added, and it is. Tried various ways of positioning the images, even wrapping them in container divs and changing the z-index of those.</p> <p>What have I missed?</p> <p>Thanks.</p>
