Why Minify CSS?

Minification is the process of removing all unnecessary characters from source code without changing its functionality. For CSS, this typically involves:

  • Removing whitespace, newlines, and tabs.
  • Removing block comments (/* ... */).
  • Removing the last semicolon in a block.
  • Stripping empty CSS rules.

Performance Benefits

CSS is a render-blocking resource. The browser must download and parse all CSS before it can render the page. By minifying your CSS, you reduce the payload size, allowing the browser to download the file faster, parse it quicker, and paint the page sooner. This directly improves metrics like First Contentful Paint (FCP) and Largest Contentful Paint (LCP).
