NEW! Version 10
Clean up your site with CSE Lite! CSE HTML Validator Lite is an award winning FREE (for personal and educational use) HTML editor and basic HTML syntax checker for Windows XP, Vista, Windows 7 and above.
CSE HTML Validator Lite can:
- Check HTML syntax (basic check only) and spelling
- Quickly change all tags and attributes to lowercase
- Automatically place quotation marks around all attribute values
- Strip HTML tags from HTML documents, leaving only the text
- Quickly change all the headers and/or footers of every page of your web site (when you design your pages using the template tool)
"There aren't many freeware programs out there these days that are this well done and useful."
"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."
"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."
