Frequently Asked Questions

What CSS syntax is supported?

We support standard CSS3 syntax including media queries, keyframes, and pseudo-selectors. Preprocessor syntax (SCSS, Less) may not format correctly — use a dedicated tool for those.

Will minifying break my CSS?

No. Minification only removes whitespace and comments — it doesn't change the CSS logic. Always keep the original unminified version for editing.
