Thumbnail hover zoom (enlarge) w/CSS3 and javascript z-axis problem

问题

Im attempting to build a series of thumbnails that enlarge on hover. My preliminary build accomplishes the enlarge/zoom part by using CSS3 transform:scale and ease-in-out. The problem is that they overlap each other because they share a single z-axis.

Can anyone assist me in creating a javascript addition to this scenario that correctly positions each thumbnail in a z-axis that makes sense, i.e. each enlarged image resizes to be on top of each other image.

Demonstration on my website here: demo Updated: Solved

Preview of code:

html:

<div style="position: absolute;" class="item hover"> 
 <a href="#"><img alt="two" src="img/posts.png"></a> 
</div>

css:

#main div.hover {
position: relative;
z-index:200;
display: block;
-webkit-transition: all 0.2s ease-in-out;
-moz-transition: all 0.2s ease-in-out;
-o-transition: all 0.2s ease-in-out;
-ms-transition: all 0.2s ease-in-out;
transition: all 0.2s ease-in-out;
background-color: #297ab1;}

#main div.hover:hover, #main div.hover_effect {
-webkit-transform:scale(1.5, 1.5);
-moz-transform:scale(1.5, 1.5);
-o-transform:scale(1.5, 1.5);
-ms-transform:scale(1.5, 1.5);
transform:scale(1.5, 1.5);}

script:

$(document).ready(function() {
    $('.hover').bind('touchstart touchend', function(e) {
        e.preventDefault();
        $(this).toggleClass('hover_effect');
    });
});

So this page uses this script to toggle the hover_effect class that increases the div's scale to 150%.

Solution: z-index:999

Also any ideas about putting a delay in the initial mouseenter without a setTimeOut?

Any suggestions and solutions are most appreciated!

p.s. This demo uses a modified version of masonry image gallery.

Thanks.
