Okay, to better explain this, I've posted an illustration of the web page layout I'm trying to build.
TOP GRAPHIC:
I have my purple footer containing a single line of text. I don't want the purple background of the footer to stop short.
BOTTOM GRAPHIC:
No matter how much content is in this footer, or how big the viewer stretches his/her window, I want the purple back to infinitely expand.
How do I make this happen? I've tried giving my footer DIV a height of 100% but with no luck. Thanks in advance, and I hope this wasn't confusing.
