Want to use a new CSS or JavaScript feature? Can I Use shows which browsers and versions support it, so you don't build something that breaks for visitors on older phones.

What you can do with it

  • Check browser support for CSS, HTML and JavaScript
  • See which features need a fallback
  • Plan for older Android and iPhone browsers

Good to know

Free to use. Look at the mobile browser columns, since most of your visitors are on phones.
