Was looking at the border-radius properties and realized you could impliment them non-equidimensionally.
In other words you can set the horizontal and verical radii independently.

So instead of just listing the code as:

border-radius: 5px;

You can set each corner separately and give them two values each, like this:

border-radius: 90px 90px 90px 90px / 30px 30px 30px 30px;

Not a big deal, but I looked around and did not see many people trying to use it, so I thought it would be something different to include on this site.
