Does it really matter? Yes, yes it does. It matters if every second counts and if you like to keep things clean. By clean I mean not having to update every webpage everytime you change the menu, background, or any other element on every page. If you used inline stylesheets you would find yourself opening every page you create and changing it.

While were talking about the "inline" let's broaden it to include the stylesheet in the header tag. This is just as useless as inline. Don't get me wrong, there are a few rare occasions you want to over ride the general stylesheet, but for almost everything else just make the css external. It solves many issues and is a lot more convient to work with when updating.

Don't Trust Me?
