Question 1

What does the CSS Minifier do?

Accepted Answer

The CSS Minifier removes comments, whitespace, empty rules, and unnecessary characters from your CSS code to reduce file size. It also shortens hex colors, simplifies zero values, and removes trailing semicolons. It handles @media queries, @keyframes, vendor prefixes, and nested rules correctly.

Question 2

Can I also beautify CSS code?

Accepted Answer

Question 3

Does the CSS Minifier handle @media queries and @keyframes?

Accepted Answer

Yes, the minifier correctly handles all CSS at-rules including @media queries, @keyframes animations, @font-face declarations, @import statements, and @supports rules. Nested structures are preserved during both minification and beautification.
