And conversely, if you want excellent performance, you'll have to cut back on the complexity of images and externals. This is the most important style goal in Web documents. The Web is so vast, it can overwhelm users who are not used to it. Following rules of thumb for consistency provides stability for the user in a visual way and gives them a sense of control. This contributes to elegance.

If the information and images that are presented in the Web documents aren't meaningful, then it doesn't matter how well laid out they are, or how good the aesthetics of the pages are. If it doesn't mean anything to the user, it's useless. Tailor your language to the users that you are targeting. This goal is more for the benefit of the author rather than the user. If you write your HTML so it is easy to read and easy to maintain, then it will greatly reduce the amount of work it takes to update them documents later on.
