Making minified CSS readable again
Production CSS is minified: whitespace stripped, newlines removed, often the whole stylesheet on one line. Excellent for download size, impossible to read. Re-indenting it gives you back the rule boundaries so you can find the selector that is fighting you.
Formatting is a presentation change only. CSS ignores whitespace between tokens, so re-indenting a stylesheet cannot alter how it renders — the rules, their order and their specificity all stay exactly as they were.
What formatting will not tell you
It reveals structure, not behaviour. When a style is not applying, the cause is almost always one of three things that indentation cannot show:
- Specificity. An ID selector outranks any number of classes. A rule further down the file only wins against a rule of equal specificity.
- Shorthand overwriting longhand. A later
background:resetsbackground-imageeven if you never mentioned it. - Inherited versus non-inherited properties.
colorflows down to children;borderdoes not.
Your browser's dev tools show the winning rule and the overridden ones struck through, which answers those questions directly. Beautifying is the step before — it makes the file navigable so you know what you are looking at.
Everything runs locally in your browser; the stylesheet is not uploaded.
