Please note folks: customers purchasing today will be entitled to the next major update "CSS HTML Validator 2020" when it is released at no extra cost.
There are many substandard websites on the Internet. Don’t let yours be one of them.
CSS HTML Validator will help you improve your search engine rankings, find and fix HTML & CSS problems and misspelled words, improve your website’s usability, and find broken links before your visitors do. To check an HTML or CSS document, just open a file or URL in the built-in editor and then press F6. The results are quickly displayed at the bottom.
In addition to HTML and CSS checking, CSS HTML Validator also includes a JavaScript linter to help you write better JavaScript.
Because CSS HTML Validator uses its own custom validation engine, it’s highly configurable. Plus, documents are validated right on your own computer, so it’s super-fast and your privacy is protected because documents are not sent over the Internet.
CSS HTML Validator is used by federal, state, and local governments (in the US, Canada, UK, and other countries), by Fortune 500 companies, and by small businesses, individuals, schools and learning institutions. It finds problems that other validators miss, and it's inexpensive, powerful, fast, includes a ton of options, protects your privacy, and generates easy to understand messages, so start using it today to improve your website!
Note: The trial download is for the CSS HTML Validator Professional Edition. Check out the feature comparison matrix to see how the Standard and Professional Editions differ.
Another note: For those wanting the pro edition, there is an option on the buy page to upgrade for $60 more!

- “This product has saved us months of bug-fixing and maintenance of our server-generated HTML, XHTML, CSS and WML pages. We have suspected for some time that Google and other search engines are getting tired of sites that do not validate or which contain spelling mistakes. Since using CSS HTML Validator, our search engine ratings have gone through the roof - there is bound to be a connection. In addition, we are now highly confident that our site looks identical in every one of the world's top browsers.”- Mac MacLaren
