How Minification Works
CSS minification reduces file size by:
- Removing comments and whitespace
- Shortening color codes (#FFFFFF → #FFF)
- Removing unnecessary semicolons
- Optimizing zero values (0px → 0)
/* Before Minification */
.container {
width: 100%;
padding: 20px;
}
/* After Minification */
.container{width:100%;padding:20px}

About CSS Minification
CSS minification is the process of removing unnecessary characters from CSS files without changing their functionality.
- Faster Loading: Smaller files load faster, improving page speed
- Bandwidth Savings: Reduced data transfer for users
- Better SEO: Page speed is a ranking factor for search engines
- Improved UX: Faster sites provide better user experience
- No Functional Changes: Minification doesn’t change how CSS works
Minified CSS should always be tested to ensure it works the same as the original.
Note: Always keep a copy of your original, unminified CSS for development and debugging purposes.
