"I downloaded CSE HTML Validator Lite about two months ago and have used it ever since. It's absolutely delightful to use - and has options for everything you can think of (and a lot that you can't!). But in spite of the options, it can be used by amateurs like myself with the default values only.

"I just downloaded the free version and used it immediately. Already I can't say enough about this product! As soon as I have a few bucks ahead I absolutely will be upgrading, and recommending CSE HTML Validator products to everyone I know who makes web pages."
