I have recently become interested in creating a CSS Rounded boxes. I have been working on a project that will use CSS to create a rounded box with a drop shadow, but  I’m not quite done with it, but here is the CodeShare link with what I have so far. right now, it’s just a box with beveled edges, but eventually the corners will be round.
research some ways of using GD to create a drop shadow.
