Hi busy boy. Divs are actually dynamic by default; it's just CSS that can stop that behavior (such as by setting a fixed width). Setting a % width returns it to a kind of dynamic behavior. It might be best if you post a screen shot of what you are aiming for and we can suggest how to go about it. Do you want the design centered? Whether yes or no, it's a good idea to wrap everything in a single div that sets the overall width--be that fixed or fluid.
