Can I use
ReferenceSearch any CSS feature and see which browser versions support it and how many users that covers.
Can I use is a browser support table site for HTML, CSS, JavaScript and other web features, made and maintained by Alexis Deveria. Search a feature and you get support per browser version, with notes and known issues.
Usage share figures come from StatCounter. You can import your own Google Analytics data in the settings to see support for your real visitors, and there is a page for comparing browsers.
Most support data lives in the public fyrd/caniuse GitHub repo under CC BY 4.0, and some features come from MDN's browser-compat-data. The site shows ads; a $1 a month Patreon tier removes them.
