Knowing HTML isn't all that's involved. You must also be able to design a page that is "user friendly" - make sure it is easy to use and not cluttered. Speed is also important, nobody likes to wait for pictures or graphics to load so use them sparingly.
Good Luck!
"user friendly" is key..I howl at the sites with no TOC..just one Loooooooooooooooooooooooooooon g page...Big time no-no..
