    <div class="visible">visible content</div>
    <div class="hidden">hidden content</div>
</div>

    $('.hidden').show();
},

You don't need jQuery to do this, you can do this in CSS.

Set .main to relative and .visible/.hidden to absolute so you can position .hidden "outside" .main, then have it displayed when you hover over .main.

jsfiddle example: http://jsfiddle.net/ZjZSk/1/

.main {
width:100px;
height:100px;
position:relative;
background:#ff0000;   
}
.main:hover .hidden {
display:block;   
}
.visible {
position:absolute;
top:0;
left:0;
width:100px;
height:100px;   
}
.hidden {
position:absolute;
top:0;
left:100px;
width:100px;
height:100px;
display:none;
background:#aaaaff;   
}
