Debug

Known issues

gotchaThe pretty function does not add newlines after void elements like <br> or <hr>.

fix

Use minify for consistent output or manually add newlines if needed.

affects: >=1.0.0

gotchaminify removes whitespace aggressively; it may break inline JavaScript or CSS if not careful.

fix

Ensure script and style content is properly handled or avoid minifying such sections.

affects: >=1.0.0

gotchaThe current version does not support formatting HTML with mixed content (e.g., text nodes with inline elements) beautifully.

fix

Consider alternatives like prettier for advanced formatting.

affects: >=1.0.0
