Why formatted HTML speeds up reviews

We ask students to format markup before they ask for help. Indented tags expose missing closers, accidental nesting inside tables, and copy-paste debris from CMS exports. Formatting first turns a vague “it looks wrong” into a specific fix.

HTML formatter with examples

Load the example one-line document, switch between 2- and 4-space indent, and watch head, body, and main nest cleanly. That readable HTML is what teams expect in code reviews.
