Frequently asked questions

What's the difference between the CSS Generator and the standalone tools?

The CSS Generator is a hub with three sub-builders (gradient, box shadow, border radius). For more specialized jobs — typography shadows, clip paths, animations — use the dedicated tools.

Are these CSS tools really free?

Yes — completely free, no sign-up, no ads. Every tool generates standards-compliant CSS you can use anywhere.

Will the generated CSS work in older browsers?

The tools generate modern CSS (CSS3+). The output uses standard property names — vendor prefixes are added where browsers still need them (rare in 2026 — most modern browsers no longer require -webkit / -moz prefixes).

Can I save / export my creations?

Each tool has a Copy button for the generated CSS. The CSS code is yours — paste it into your stylesheet directly.
