About CSSGen.dev

CSSGen.dev is a free set of 30 CSS generators. You move a control, the real property renders on a real component, and you copy code that is ready to paste into a stylesheet.

Why it exists

Most CSS generators show you a picture of a result. You tune a shadow against a grey square, copy the rule, paste it into your own component and discover it looks wrong there. CSSGen.dev previews every property on the kind of element you will actually apply it to, so what you see is what ships.

The other reason is the Stack. A real component rarely needs one property. It needs a radius, a shadow, a gradient and a filter at once, which usually means four generators and four copy-pastes that you then merge by hand. The Stack layers them onto one element and merges them into a single declaration.

Everything runs in your browser

There is no account, no sign-up and no server-side processing. The generators are JavaScript running on your own machine. Your colours, your settings and your saved presets are kept in your browser’s local storage and never transmitted. What that means in detail is set out in the privacy policy.

A practical consequence: the site works offline once loaded, and a share link carries your settings in the URL itself rather than on a server.

Where the browser-support data comes from

Each generator shows the first stable browser version with unprefixed support, and a Baseline status of widely available, newly available or limited. That data is compiled from the web platform’s own compatibility sources and checked against the specifications, then shipped as a static table you can read in full on the browser support page.

It is a snapshot, not a live feed. Browser support moves, and a table that is right today can be wrong in six months. If you find an entry that has gone stale, tell us and it gets corrected.

How mistakes get fixed

A generator that produces wrong CSS is the most serious kind of bug this site can have, because the output goes straight into someone’s production stylesheet. Every generator has a Share link button that encodes your exact settings into the URL, so a bug report can carry the precise configuration that broke rather than a description of it. That is the fastest route to a fix.

Using what it generates

Everything the generators produce is yours. It is free for personal and commercial projects. Attribution required.
