W3 Validator

The W3 Validator is a tool for web designers. You simply enter the URI for your webpage or upload it to them. It automatically picks up most syntax errors, keeping your document in line with standard rules. If it is valid, you are authorized to place a image stating the page has been validated. You can see the image to the left. This image is also a link to re-validate the page, that anybody can click. It give a detailed description of the error, its causes, and solutions. Definitely a tool to look into. http://validator.w3.org/
