Whenever you are using Joomla! to construct a large page that will have many visitors, it can become important to keep the page loading time as short as possible. In the Beez template, I integrate several CSS files: one for positioning, one for the distances, one for the colors, and one for the different Internet Explorer versions. These files make it easier for designers to handle and understand. But for each file, you need to send a request to the servers, which affects the performance.
