Does it handle self-closing tags?

Yes. Void elements like , , , , etc. are handled correctly — they don't increase the indent level.

Will it change my HTML's behavior?

No. The beautifier only adds/removes whitespace for formatting. The HTML structure and behavior remain identical.

Can I beautify HTML with inline CSS/JS?

The tool formats the HTML structure. Inline CSS and JS within tags are preserved as-is. For CSS/JS formatting, use our dedicated CSS Minifier or JS Minifier tools.
