What this tool does

This CSS formatter makes stylesheets easier to scan by separating selectors, declarations, media queries, and keyframes into consistent blocks.

Processing logic: tokenize braces and semicolons, keep comments if selected, indent nested blocks, optionally sort declarations, and analyze selector and property counts.

Formatting should preserve CSS behavior, but always review generated code when using advanced CSS syntax.

Example

Try the sample input, run format css, and compare the before-and-after structure in the result panel.

Use cases

  • Clean code before review or sharing.
  • Prepare structured text for documentation, snippets, or production workflows.
  • Check size, line count, structure, and quality before exporting.

Tips for better output

  • Group related selectors to improve maintainability.
  • Avoid overly specific selectors when possible.
  • Remove duplicate declarations before minifying production CSS.

FAQ

How do I format CSS automatically?

Paste CSS into the tool and run the formatter to split rules, declarations, braces, and media queries into readable lines.

Should CSS properties be sorted alphabetically?

Sorting helps scanning large rules, but some teams prefer logical grouping such as layout, spacing, typography, and colors.

Why is my CSS hard to maintain?

CSS becomes hard to maintain when selectors are too specific, rules are duplicated, media queries are scattered, or declarations overwrite each other.

Can CSS formatting change page layout?

Safe formatting should not change layout because it changes whitespace, not selectors or property values.

How do I improve CSS maintainability before minifying?

Format the CSS, remove duplicates, reduce specificity, group related rules, and then use a minifier for production output.
