Lowest common denominator. I am a huge fan of
http://www.csszengarden.com, and have contributed a few styles, and the grim reality is many internet users still use IE, and have monitors with resolutions set at 800x600. A web design that will display properly at 800x600 and uses {margin:0 auto;} will look great at 800x600 as well as any size above that. A site designed graphically to display at 1024x768 will have horrible horizontal scroll bars in the viewport of a user set to 800x600. I am just a huge fan of standards compliance and trying to make sure everyone sees the same thing. If you know that all your visitors have at least 1024x768, or you don’t really care if the 800x600 crowd (probably a good portion of the world outside US,UK) can’t see your site the way you intended it you should probably design for 1024x768. The choice is up to the designer, but like I said, I really dig universal web standards and lowest common denominator. I think it would be cool if in a later revision of the CSS standard, or possibly just a JavaScript function, there was a screen resolution check so you could potentially load a different css for different screen resolutions.
here are some guidelines from ZenGarden:
* Have you tested in as many browsers as you can? Windows and Mac? (a good answer: yes)
* Can you scale your fonts up to 150% in Mozilla? (a good answer: yes)
* Do you get a horizontal scrollbar at 800x600? (a good answer: no)
