What is HTML formatting?

HTML formatting (beautifying) makes markup readable with consistent indentation and line breaks, which helps reviews, debugging, and collaboration.

What is HTML minification?

HTML minification removes unnecessary whitespace and optional comments to reduce payload size. It can improve load times and bandwidth usage while keeping markup valid.

We give lightweight warnings when markup looks fragmentary. Formatting is best-effort and won’t hard-block.
