Web Site Layout
When designing a website, there are many factors to consider when designing the sites layout.  Should it fit the screen, or should it be fixed width?  Should I center it or should it be aligned left?  What fonts should I use?  So on and so forth.

I'm not a designer by any means, but I have learned quite a few things about design from working at a design shop.  Designers tend to like fixed width sites because they are use to working in a fixed document space like Photoshop.  They want their designs to look exactly the way they laid it out in their graphics program.  The only problem with this is that it is not possible to have an exact translation to the web from a graphics file.  Every browser will render a page slightly differently.  Fonts won't look the same, margins and paddings will be slightly misinterpreted, and the user's screen will have a different resolution then the nice high resolution monitors the designers have.
