Format nested HTML without changing the document structure
HTML Formatter turns compact or uneven markup into an indented tree, making parent-child relationships, attributes, and closing tags easier to inspect during reviews.
What to check
Check embedded templates, preformatted text, and whitespace-sensitive inline content after formatting. A readable layout can expose a misplaced closing tag, but it does not prove that the document is valid or accessible.
Worked example
A single-line card containing a section, heading, and paragraph becomes a three-level outline, so the section boundary and the two sibling elements are visible immediately.
