Code Examples

CSS - Before Minification

/* Header Styles */
.header {
  background-color: #ffffff;
  padding: 20px;
  margin: 10px 0;
  border-radius: 5px;
}

/* Navigation Styles */
.nav {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

.nav a {
  color: #333333;
  text-decoration: none;
  padding: 10px 15px;
}

CSS - After Minification

.header{background-color:#fff;padding:20px;margin:10px 0;border-radius:5px}.nav{display:flex;justify-content:space-between;align-items:center}.nav a{color:#333;text-decoration:none;padding:10px 15px}

JavaScript - CSS Minification

// Simple CSS minifier function
function minifyCSS(css) {
  return css
    .replace(/\/\*[\s\S]*?\*\//g, '') // Remove comments
    .replace(/\s*:\s*/g, ':') // Remove spaces around colons
    .replace(/\s*;\s*/g, ';') // Remove spaces around semicolons
    .replace(/\s*,\s*/g, ',') // Remove spaces around commas
    .replace(/\s*\{\s*/g, '{') // Remove spaces around opening braces
    .replace(/\s*\}\s*/g, '}') // Remove spaces around closing braces
    .replace(/\s+/g, ' ') // Replace multiple spaces with single space
    .trim(); // Remove leading/trailing whitespace
}

// Usage
const css = `.header { color: red; margin: 10px; }`;
const minified = minifyCSS(css);
console.log(minified); // ".header{color:red;margin:10px}"
