Css background extending layout

[vinnt2]

Hi there I've always wondered how people created their own layouts and then somehow coded it to act like an extending table? Like a table that will just keep extending like no matter how much text they put into it? Here's a link with an example of what I'm talking about http://www.neopets.com/~yurbleburble_26 If anyone could help me please leave me a message! Thank you!

Usually you just use the CSS selector:

overflow: auto;

element which causes the div containing the content to just keep on going when there's new content introduced instead of having a fixed height.

so, something like this:

#contentcontainer {
overflow: auto;
width: 750px;
padding: 10px;// so it doesn't have text bumping into the edges
}
