Examples

1. Beautifying Minified Production CSS

Frontend Developer

Background

A developer needs to debug a layout issue on a live website but only has access to the minified production stylesheet.

Problem

The CSS is compressed into a single line, making it impossible to read or locate specific selectors.

How to use

Paste the minified CSS into the input area, set the indentation size to 4 spaces, and enable blank lines between rules.

indentSize: 4, newlineBetweenRules: true

Outcome

The CSS is formatted into a readable structure with clear indentation and spacing, allowing the developer to locate and fix the layout bug.

2. Formatting Grouped Selectors for Code Review

Web Designer

Background

A designer is preparing a stylesheet with multiple grouped selectors for a team code review.

Problem

The grouped selectors are written on a single line, which violates the team's style guide.

How to use

Paste the CSS code, check the 'Newline Between Selectors' option, and set the indentation to 2 spaces.
