CSS Formatter

📖 Description

1. Why Do You Need an Online CSS Formatter?

While CSS is simple, its organizational structure directly impacts project maintainability:

• Restore Readability: Convert single-line minified code (.css) back into multi-line, indented, and well-structured source code for easy modification.
• Unify Team Style: Automatically handle spaces between selectors, property names, and values, and standardize the line break position for braces {}.
• Performance Optimization: Reduce file size by removing unnecessary spaces, comments, and blank lines, improving website loading performance.
• Property Error Checking: After formatting, it's easier to spot missing semicolons ; or unclosed brackets.

2. Core Features Explained

Our tool offers not just simple indentation but also deep CSS processing capabilities:

A. Two Core Modes (Format & Minify)

• Beautify (Format): Add appropriate line breaks and indentation to make the code hierarchy clear.
• Minify: Remove all unnecessary whitespace and comments, compressing CSS to the smallest size, suitable for production deployment.

B. Intelligent Formatting Configuration

• Indentation Style: Supports custom 2-space, 4-space, or Tab indentation.
• Single-line/Multi-line Mode: Choose whether to place each property on a separate line or combine simple rules on the same line.
• Blank Line Cleanup: Automatically remove excess blank lines between selectors, making the code compact and orderly.

C. Property Normalization

• Auto-add Semicolons: Ensures every property ends with a semicolon, preventing syntax errors.
• Case Conversion: Optionally convert all selectors or property names to lowercase for code consistency.
• Colon Space Optimization: Standardizes adding a space after the colon (e.g., color: red; instead of color:red;).

D. Real-time Syntax Highlighting Editor

• Supports highlighting for the latest CSS3 properties (e.g., Flexbox, Grid, Variables), provides real-time preview of formatting results, and supports code folding.
