Great method for styling images with CSS
I wrote this post a while back. The content can still be relevant but the information I've linked to may not be available.
Web Designer Wall has published a clever CSS decorative gallery technique for styling images with CSS. The use of an absolutely positioned
<span> element inside a relatively positioned container element and the use of transparent .png images enables a variety of decorative images to be used as 'overlays' for 'parent' images.
I particularly like the pop-up example which uses an
<em> tag to display a title for each image on hover.
