FAQ

CSS Tools: common questions

What belongs in CSS Tools on Toolspire?

CSS Tools is one collection on justtools.info. Open any tool and the page tells you whether the work stays on your device or a public lookup is required.

Can I use the generated code in my projects?

Yes. The code you copy is yours to use in any project, personal or commercial, with no attribution and no licence to buy.

Will the CSS work in every browser?

Each tool says what its CSS needs and writes fallbacks where support is missing: a solid background where blur is not available, a small script where scroll-driven animations are not, and rules that respect the reduced-motion and reduced-transparency settings people choose on their devices.

Where is the CSS to Tailwind converter?

With the developer tools: CSS to Tailwind turns any CSS you paste into Tailwind classes.
