Okay, thank you for the follow-up responses. I will tamper with things a little bit tonight (or tomorrow) and let you guys know how it goes. What you're saying makes sense and I think what I pictured in my mind is the possibility of setting the div width as a percentage of the entire browser window. I will have to see how this affects the text within the divs, etc, especially if DIVs inside of the outer DIV are in fixed px or em width.
In case you couldn't tell I'm a bit of a beginner at this but having helpful people like you guys on this forum saves me a bunch of time and heartache. Thanks for the responses!
