An example would be:

I want to know how to make the edge cut off like that instead of go on like in most div layouts.

I'm sorry if this is the wrong forum for something like this, because I don't know what sort of coding is used and if it falls under CSS or tables, or anything else.

Thanks ahead of time!

Just a footer tag using div and css

With CSS you set up the way you want it to look.

<div id="footer"></div>

Oh, alright. I'll try that!
