Information

Whilst producing my previous demo I cam across a way to have :focus, which is allowed on elements that accept keyboard events or other user inputs, to be applied to other elements.

In the above demo, which by the way does not validate, I have applied :focus to the four images so that I can style a mouse click on the 'thumbnail' to produce the large image.

So click the thumbnail to show the large image, then click anywhere on the page to shrink this back to the thumbnail. You can also tab forward and Shift/tab backwards through the images.

This comprised just two lines of style:
.popup {height:96px; cursor:pointer; display:inline; margin-right:3px;}
.popup:focus {position:absolute; height:auto; z-index:100; background:#fff; padding:20px; outline:1px solid #aaa;}

..and just the four images without any extra markup. No links and no wrapping elements:
<img class="popup" src="popbox/pic1.jpg" alt="" tabindex="1" /><img class="popup" src="popbox/pic2.jpg" alt="" tabindex="1" /><img class="popup" src="popbox/pic3.jpg" alt="" tabindex="1" /><img class="popup" src="popbox/pic4.jpg" alt="" tabindex="1" />

Works in IE8+, Firefox, Opera, Safari and Chrome.
