HTML Formatter

Markup that has been generated, minified or edited by several people stops showing its own structure, and this re-indents it so nesting is visible again, with block elements on their own lines. Content and attributes are preserved exactly — only the whitespace between tags changes — so the formatted document renders as the original did. It is most useful when you have inherited a template and need to find where a container actually closes, or when a fragment copied out of dev tools needs to go back into a repository readable. Two limits matter. Whitespace is meaningful inside `<pre>` and `<textarea>`, and between inline elements it can affect rendered spacing, so check those areas after formatting rather than assuming nothing moved. And this tidies markup rather than repairing it: an unclosed tag stays unclosed and will not be reported. Formatting two versions the same way before comparing them is also the quickest way to see what genuinely changed.
