You may also want to use EmEditor, a powerful Windows text editor that now comes with a more recent special build version of CSS HTML Validator Lite.

Find bad or misspelled tags and attributes
Find missing end tags
Find other HTML & XHTML syntax problems
Find bad CSS properties and values
Check spelling with the built-in the editor
Quickly change all tags and attributes to lowercase
Automatically place quotation marks around all attribute values
Remove (strip) HTML tags from HTML documents, leaving only the text
Protect your privacy (because it doesn't transmit your documents over the Internet)
"There aren't many freeware programs out there these days that are this well done and useful."
- Tim Matheson, CSE HTML Validator User
"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 have tried several other validators before and none comes near it for ease of use, flexibility, and thorough reliability. When I develop to the stage of needing the even more powerful edition, I won't bother to look elsewhere, as I'm confident this product will be of the highest standard also. Well done, and thanks."
- Phil Taylor, CSE HTML Validator User
