I’m sure the solution is simple and I’ll kick myself for not seeing it, but…
I need the background image at the bottom of each of those divs (the part that looks like an arrow pointing toward the photos). Nothing I’ve tried is working. I don’t want the left/right borders to extend past the image.
(Note the above is over-ride not replacement code)
I used :after to place the image at the bottom which is supported from IE8+. IE7 and under just get a border-bottom instead.
