It's always a pleasure to click on a link and see a pearl g-string as the sample item.
there's a slight pixel shift on the hover... could it be the listing and listing2 css class?
.listing { border: 1px solid; padding: 7px; [snip]
.listing2 { padding: 7px; border: 1px solid #B18BA2; [snip]
although both have padding defined, could the fact that listing2 has a color defined for the border make a difference? It looks weird with the padding shift...
I noticed this in Firefox and Safari.
