CSS Minifier & Stylesheet Optimizer

Effective CSS minification removes non-functional bytes while preserving stylesheet cascade rules:

• Comment Removal: Strips developer comments (/* ... */) that are ignored by browser layout engines.
• Whitespace & Line Break Elimination: Removes indentation spaces, tabs, and newline characters, collapsing CSS rules into a single continuous stream.
• Semicolon Optimization: Strips the optional trailing semicolon before closing declaration braces (e.g. { color: red; } $\rightarrow$ {color:red}).
• Zero Value Simplification: Replaces dimensional zero units (e.g. 0px, 0em, 0rem, 0%) with unitless 0 according to W3C CSS specifications.
• Hex Color Compression: Shortens 6-digit hexadecimal colors to 3 digits where applicable (e.g. #ffffff $\rightarrow$ #fff, #000000 $\rightarrow$ #000).

CSS is a render-blocking resource. Reducing stylesheet byte size reduces network transfer time and accelerates DOM construction, directly improving Google Core Web Vitals scores.
