Understanding CSS Formatting

What is CSS Beautification?

CSS beautification transforms compressed or poorly formatted stylesheets into clean, readable code with proper indentation and line breaks. This makes CSS easier to:

  • ✓ Read and understand quickly
  • ✓ Debug and identify issues
  • ✓ Maintain and update over time
  • ✓ Review in version control

What is CSS Minification?

CSS minification removes all unnecessary characters from stylesheets without changing functionality. The minified output reduces bandwidth by removing:

  • ✓ Whitespace and line breaks
  • ✓ Comments (optional)
  • ✓ Unnecessary semicolons
  • ✓ Extra spaces around selectors

CSS Formatting Example

Minified CSS:

.container{max-width:1200px;margin:0 auto;padding:0 20px}.btn{display:inline-flex;padding:10px 20px;background:#007bff;color:#fff;border-radius:4px}

Beautified CSS:

.container {
  max-width: 1200px;
  margin: 0 auto;
  padding: 0 20px;
}

.btn {
  display: inline-flex;
  padding: 10px 20px;
  background: #007bff;
  color: #fff;
  border-radius: 4px;
}
