Why Minify CSS?
CSS minification is the process of removing all unnecessary characters from CSS files without changing their functionality. This includes removing whitespace, newlines, comments, and sometimes optimizing certain patterns to reduce file size.
Minified CSS files are smaller, which means they download faster, leading to improved website performance and better user experience, especially on slower connections.
What is a CSS Minifier & Beautifier?
A CSS minifier and beautifier is a dual-purpose tool that helps developers optimize their CSS code for different environments. The minifier compresses CSS by removing unnecessary characters, while the beautifier formats CSS with proper indentation and spacing for better readability during development.
