Frequently asked questions

Does beautifying change how the HTML renders in a browser?

No. Adding whitespace and indentation does not affect how HTML is displayed. Browsers ignore formatting whitespace in most contexts.

Can it format HTML that contains embedded CSS or JavaScript?

The tool focuses on HTML structure. Embedded CSS and JavaScript may be partially formatted but dedicated beautifiers for those languages will give better results.

Does it validate the HTML?

The tool formats what you provide. It may not flag all HTML errors, so use a dedicated HTML validator for full validation.
