Frequently Asked Questions

Basics

What is CSS formatting?

CSS formatting is the process of organizing CSS code with proper indentation, spacing, and line breaks to improve readability and maintainability.

Why should I format my CSS?

Formatted CSS is easier to read, debug, and maintain. It helps team members quickly find and modify styles, especially in large stylesheets.

Features

What formatting options are available?

Our tool offers beautification (adding proper indentation and spacing) and minification (removing whitespace for production use).

Does the tool support CSS preprocessors?

This tool supports standard CSS3 including media queries, keyframe animations, and nested at-rules. For SCSS/LESS preprocessing, use a dedicated preprocessor first.

Examples

Example: Format a simple stylesheet

Input (Minified):

body{margin:0;padding:0;font-family:Arial,sans-serif}

Output (Formatted):

body {
  margin: 0;
  padding: 0;
  font-family: Arial, sans-serif;
}

Example: Media queries

Input:

@media(max-width:768px){.container{flex-direction:column;padding:0 16px}}

Formatted Output:

@media (max-width: 768px) {
  .container {
    flex-direction: column;
    padding: 0 16px;
  }
}

Troubleshooting

Why is my CSS not formatting correctly?

Ensure your CSS syntax is valid: all rules should have matching braces, properties should end with semicolons, and strings should be properly quoted.

Does this tool validate my CSS?

This tool focuses on formatting and minification. It will format valid CSS but won't flag property errors or deprecated values. Use a CSS validator for syntax checking.
