Remember yellow copy and white copy are hard to read and not printable. W hite, or light colors, are best for background. Dark backgrounds can be used on home page only. Use color text only for emphasis. Keep site consistent, don't have different color backgrounds for every page.
Every page needs a headline and a title.
No side to side scrolling bar to view pages. Design all pages to fit a 15 inch screen. The site must be unique and have information that you can't find anywhere else. Do not use more than 2 dividers per page Bottom of every page must have top of page and home page link. Make your site user friendly and easy to navigate, don't make it a guessing game when someone visits your site.
