CSS minification is the process of removing all unnecessary characters from CSS source code without affecting its functionality. This typically includes removing comments, whitespace (spaces, newlines, tabs), and sometimes shortening color codes or other values.

Benefits:

• Reduced File Size: Smaller CSS files load faster, improving website performance.
• Faster Parsing: Browsers can parse smaller files more quickly.
• Lower Bandwidth Usage: Saves bandwidth for both the server and the end-user.

This tool provides basic CSS minification by removing comments and redundant whitespace. For advanced optimization, dedicated build tools or online services are recommended.
