Struggling with getting the content area on my web page sized and aligned correctly. I want it to utilize all the vertical visible screen space, leaving 80px at the top and 20px at the bottom. Sometimes, the page may extend further down, requiring scrolling to view.
For example: a) On a screen measuring 800x600, the content area should be 500px high b) On a screen measuring 700x1100, the content area should be 1000px high
The website is created using HTML and CSS.
