Questions fréquentes

Does it validate my HTML?

Not strictly. It formats the markup as-is. For validation use the W3C validator or a linter like htmlhint.

Does it preserve inline scripts and styles?

Yes. Content inside <script> and <style> blocks is preserved and indented sensibly.

Is my HTML uploaded?

No. Formatting runs entirely in your browser.

Why did some whitespace change inside <pre>?

The beautifier is careful with <pre> and <textarea> content, but if you notice a change, please report it.
