One of Tuts+ editors, Jeffery Way, just released the really awesome tool, Prefixr, that combats the stress of cross-browser compatibility. It's a simple tool used to make your CSS code cross-browser-prepared. A problem occurs unexpectedly and unnoticeable, though, which you must be aware of.
You are initially finished with your CSS. You've added all of the necessary fixes that will make your website's design stick out perfectly; but when you go to use Prefixr, for easy cross-browser compatibility, and you've actually done that, you realize something isn't right with your original work.
It's because you've either been code-jacked, some lines were confusing to the Prefixr, or worst: one color or another became an entirely different color! So, when you put your code into the Prefixr, make sure to manually check your code. Otherwise, your website is bound to be corrupted in some small but jeopardizing way.
