Markup with no breathing room

A copied template, a generated block, or a hand-edited stylesheet has lost all indentation. You cannot tell where a tag or rule ends. Re-indenting by hand is error-prone.

Indent it in place

Use the HTML / CSS Beautifier, switch between HTML and CSS mode, and paste your markup. Tags nest by indentation (HTML) or braces by indentation (CSS) so the hierarchy is visible at a glance.

Worked example

<div><p>Hello</p><span>World</span></div> expands into a readable tree. A flat CSS rule block gains per-property lines and brace alignment.

Boundaries

  • Basic indentation only — it does not validate markup or resolve malformed tags.
  • For strict, spec-compliant formatting, use a dedicated HTML/CSS formatter in your build.

FAQ

Will it fix broken HTML? No — it only indents what parses. Validate separately if structure is wrong.

Self-closing tags? Common void elements (br, img, input…) are treated as non-nesting.
