Browser Compatibility and caniuse.com
Check feature support across browsers on caniuse.com, understand vendor prefixes, and use polyfills or fallbacks when needed.
Why Does Compatibility Matter?
Different browsers implement web standards at different speeds. A CSS property or JavaScript API available in Chrome 130 may not exist in an older Safari or Firefox version. Testing and planning for compatibility prevents broken experiences for your users.
caniuse.com — Your Compatibility Reference
Go to caniuse.com and type any CSS property, JavaScript API, or HTML attribute. You'll see a colour-coded support table across all major browsers and their recent versions, along with usage statistics and notes on partial support.
