The body text of a web page should be 12 point Times New Roman. Body text should use a white background with black or navy text . Deep background colors, background patterns, or background textures obscure content and frustrate visitors. Because web documents are viewed online, web pages should be limited to one or two pages. Break long documents into multiple web pages, and use hyperlinks to navigate between them.
Many users leave sites that require obscure plug-ins.
Don't use frames. They unnecessarily complicate pages and are confusing to the average user. Use tables instead. Contact the Webmaster's Office for exceptions. Never link directly to index.html, index.htm, default.htm, or default.asp.
