title: How to make the height REALLY 100%
body: <p>in CSS when you set something's width or height to 100% it really only sets it to 100% of the browser window. Is there any way to make it 100% of the whole page?</p>
  
  <p>Let me rephrase: I want this element (a div) to take up the ENTIRE page, no matter how much you scroll. Having parent elements with 100% size and 100% width doesn't work because they are treated the same way. I'm beginning to think that I might have to use JS to get the height of the page and then absolutely define that.</p>
