CSS Minifier

Stripping whitespace and comments is the obvious part of minifying CSS, but the specific size gains come from elsewhere, shortening a color value like #ffffff down to #fff, dropping a unit off a zero value since 0px and 0 render identically, and combining separate margin or padding properties into a single shorthand line, optimizations a naive whitespace-only stripper never catches. This tool minifies CSS by removing whitespace and comments while also applying these CSS-specific size reductions, rather than only stripping formatting. Useful for shrinking a stylesheet for production beyond what basic whitespace removal alone achieves, shortening color values and zero units automatically instead of hunting for them by hand, or minifying CSS with shorthand property optimization included rather than left for a separate pass.
