Validate Your HTML
So you've made your webpage with fancy inline images and styled text. All you have to do now is let the people come, right? Well, not just yet, first you have to validate your html.
"Why do I need to do that? My webpage looks fine in browser X?" Looks can be deceiving. Browsers use "error correction", this means if it encounters invalid HTML the browser "guesses" what should really be there. No two browsers "guess" the same and in the end your page could look shockingly different from browser to browser.
Some browsers aren't as forgiving and might not display a part of your page, or could just give up and not display your page altogether! When the W3C has taken time to develop a universal standard for HTML, why would you want to go out and write your own HTML? You wouldn't; if you did you would be promoting a destructive element on the Internet. Now think about it, would you want to deliberately destroy the Internet?
The argument is often made against validation concerning the number of successful websites with invalid markup. The flaw in this reasoning is that the success of a site is largely due to good "look and feel", content and promotion. With that in mind, imagine how much more successful these websites could be if their pages rendering consistently because of valid markup.
