Does anyone here know much about CSS and HTML? I've hit a slight snag. I'm trying to centre a box (have it as a span with a div inside - a box in a box) both horizontally and vertically. I can get it to work just fine in Firefox, but IE won't let me do it. I've tried everything I can think of, I've looked for help online and tried what I found. Nothing. Does anyone know how to do it?
