Format, organize, and beautify CSS code with property sorting, indentation control, and minification.
CSS Formatter & Beautifier rewrites pasted stylesheet text into a consistent layout: rules are separated clearly, declarations are indented, and controls can change indentation, sort properties, or produce a minified form. It handles the structural parts specific to CSS, including selectors, declaration blocks, and at-rules. The easy mistake is treating formatting as automatically semantics-preserving. Property order can matter when a block contains duplicate declarations or overlapping shorthand and longhand properties, so property sorting deserves review before replacing working source.
Beautifying changes the presentation of CSS around selectors, braces, semicolons, and declaration blocks. Indentation control determines how nested content, such as rules inside @media or @supports, is aligned. Formatting is not syntax validation: a tidy result can still contain an invalid selector, unsupported value, or malformed at-rule that a browser ignores.
Property sorting reorders declarations within each rule; review blocks that deliberately put fallbacks, duplicates, shorthand, and longhand declarations in a chosen sequence. Minification takes the opposite presentation goal from beautifying, returning a compact stylesheet with nonessential layout reduced. Neither operation answers whether a property is supported in target browsers or whether selectors match the intended elements.
No. Many declaration blocks are unaffected, but CSS source order resolves duplicate declarations and shorthand/longhand conflicts. For example, `margin-top: 1rem; margin: 0;` does not produce the same top margin when reversed. Leave sorting off or review the diff whenever order expresses fallbacks or intended overrides.
No. Its job is to rewrite layout, order declarations when requested, and compact CSS. A clean-looking result does not establish that selectors, at-rules, values, or nesting are accepted by a browser. Use a CSS validator and test in the browsers you support when syntax correctness or compatibility matters.
