Compress stylesheet syntax without redesigning the cascade
CSS Minifier removes comments and unnecessary spacing around selectors, braces, declarations, and punctuation to shrink a stylesheet’s delivery form.
What to check
Retest custom properties, calc spacing, hacks, data URLs, and concatenated files. Minification does not remove unused CSS or resolve specificity conflicts, so the original cascade still determines the result.
Worked example
A readable .card rule with display and gap declarations becomes one compact rule, while the selector and both property values remain unchanged.
