Why Format Your CSS?

How It Works

Our CSS formatter processes your code with these steps:

Parse CSS

The code is parsed into a structured tree (rules, selectors, declarations).

Apply Indentation

Rules are indented based on nesting, using the number of spaces you selected.

Output Readable Code

The result is a beautifully formatted CSS block, ready for review or editing.

Frequently Asked Questions

Sample

@media (max-width:350px){.bd-examples{margin-left:-.50rem;margin-right:-.50rem}.bd-examples>[class^="col-"]{padding-right:.50rem;padding-left:.50rem}}

Converts to:

@media (max-width:350px) {
 .bd-examples {
  margin-left: -.50rem;
  margin-right: -.50rem
 }

 .bd-examples>[class^="col-"] {
  padding-right: .50rem;
  padding-left: .50rem
 }
}

Best Practices

Use consistent indentation across your entire project
Combine with a linter (e.g., stylelint) for even cleaner code
Format before committing to version control
Keep your CSS files under version control in formatted state

Formatting Benefits

Makes a missing brace or selector easier to see than in one compressed line
Makes code reviews faster and more effective
Helps new team members understand the codebase quickly

A CSS formatting example

Paste this compressed rule and choose 2 spaces:

@media (min-width:40em){.card{display:flex;gap:1rem}.card h2{margin:0}}

The formatter expands the media query, puts each declaration on its own line, and indents the nested rule. It uses the js-beautify CSS formatter. It does not compile SCSS or LESS, and it does not check whether gap is supported by a particular browser.

A missing closing brace usually remains a missing closing brace. Read the formatted result before replacing the source file.
