the link Kaladan posted (themejug galao theme) shows thumbnails with rollovers you can click on to show the post.
The CSS solution you posted in this thread resembles the rollover effect perfectly except for the fact that the thumbnail cannot be clicked anymore although the image is in a tags (see my fork of your script).
only the outer area that is not covered by the rollover can be clicked. I’d like to know how make the whole thing clickable like it’s in the galao theme. Preferably without JS.
