About This Tool

The CSS Code Formatter ingests raw CSS and outputs a consistently styled stylesheet. It is designed for developers who want fast, repeatable formatting without manual edits. Conceptually, it parses CSS into a structured representation, applies formatting rules, and emits clean, human-readable code that aligns across files and teams.
Key features include indentation control, brace handling, and optional property sorting. It preserves comments, normalizes line breaks, and can enforce blank lines between blocks. Users can configure 2- or 4-space indentation and enable or disable property sorting to enforce consistency.
Workflow and benefits: paste CSS into the tool, set rules, run formatter, and copy the output. It integrates into CI pipelines via a command-line wrapper or API, enabling automated style checks. This reduces review time, minimizes stylistic disputes, and improves overall code quality.
Use cases include onboarding new codebases, preparing pull requests, auditing legacy CSS, and enforcing a team standard for cross-project style.

Frequently Asked Questions

Find Quick Answers

Does it preserve comments?

Yes. Comments are preserved and positioned to maintain readability after formatting, avoiding unintended removals or reordering. The formatter keeps inline and block comments in place and applies consistent indentation around them, ensuring the final CSS remains faithful to the original intent while achieving uniform style.

Can I customize indentation?

Yes. Indentation can be set to 2 or 4 spaces, and the formatter applies the chosen width consistently across selectors, blocks, and declarations. It does not alter the semantic content of the CSS, only whitespace and line breaks.

Does it format SCSS or LESS?

No. The formatter targets standard CSS syntax and does not fully parse or restructure preprocessors such as SCSS or LESS. If you work with preprocessor files, run a preprocessor first to generate CSS and then format that CSS with this tool.

Can it sort properties?

Yes, property sorting is optional. When enabled, declarations are reordered by property name while preserving values and comments. If disabled, the original declaration order is preserved to respect intentional grouping or cascading behavior.
