How do I validate my site? Once you've finished your site, you can validate your HTML code with an online validator to check your code to see if you've made any mistakes or not (I've provided a place to validate your code below). In order to check your code, you'll have to include a doctype and identify a charset in your code. This is what mine looks like:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

To use either of these validators, type in your URL in the space provided, and hit "enter." Either your code will be free of mistakes, or the validator will point out which mistakes you've made. If you've made mistakes, the validator will tell you what the mistake is, but not how to fix it.
In order to better understand how to fix your mistakes, running your code through a program like CSE HTML Validator Lite would be a good idea. This program is available free for download.
If you would like to convert your code to xml, you can use a program like HTML Tidy. After using it, I would suggest running your site back through one of the above listed validators.
