Help with Colorbox lightboxes 'already visted' link
I've been trying to do this with CSS and had some great help from the guys in the CSS forum, but we found out it might be more possible with PHP.
I am using Colorbox, a lightbox JsQuery, to load an external PHP file. Basically, when a user has clicked on a thumbnail image and the page opens up the colorbox, when the user then closes it, I would like the padded background of the thumbnail to be a different color - almost like a 'visited' state (as I say, we tried it with CSS but couldn't get it to work entirely).
Is there some PHP I can assign that says: if div class is clicked, display padded bg color #000000...?
Hope this makes sense!
Thank you and I hope to hear from you!
