Frequently asked
How do I check if a CSS feature is supported in my target browsers?
Use the search and filters on this page to find any CSS property, selector, at-rule, or function. The table shows the minimum version required in Chrome, Firefox, Safari, and Edge. Match these against your target browser versions to determine support. Also check the Baseline status badge to see overall adoption maturity.
What does Baseline status mean?
Widely Available means the feature shipped in all major browsers at least 2.5 years ago—safe for production without fallbacks. Newly Available means it recently reached all major browsers—consider your audience. Limited Support means some browsers don't support it—you need fallbacks or polyfills. Learn more at web-platform-dx.
Do I need a fallback for this feature?
If Baseline shows "Widely Available", no fallback is needed—all major browsers support it. If "Newly Available", consider your audience: if most users are on recent browsers, you're fine; otherwise add a fallback. If "Limited Support", always provide a fallback. Check your analytics to see what browser versions your actual users run.
What's the difference between browser support percentage and Baseline?
The global usage percentage (from caniuse) shows what percent of worldwide web traffic can use the feature right now. Baseline shows adoption maturity across major browser engines. A feature at 70% usage might still be "Limited" if Safari doesn't support it. Both matter: usage for real-world reach, Baseline for cross-browser compatibility.
How can I learn more about a specific CSS feature?
Click any feature name in the table to go to its detailed reference page, which includes examples, common pitfalls, syntax details, and links to MDN, caniuse, and the official spec. The reference explains how to use the feature and what to watch out for.
Why should I care about browser engines?
All major browsers use one of four engines: Blink (Chrome, Edge, Brave), Gecko (Firefox), WebKit (Safari), or their own. When a feature ships in all four engines, it works everywhere. If a feature only works in Blink, you're excluding Firefox and Safari users. This page groups support by engine so you see what actually works across browsers.
What are the four browser engines?
Blink powers Chrome, Edge, Brave, Opera, and most Chromium-based browsers. Developed by Google, it was forked from WebKit in 2013 and powers the majority of web traffic.
Gecko powers Firefox and Firefox-based browsers. Developed by Mozilla, it's open-source and known for strict standards compliance and unique features Firefox pioneers.
WebKit powers Safari, iOS browsers, and some Android browsers. Developed by Apple, it's open-source but required for all iOS/iPadOS apps due to App Store restrictions. This makes it critical for mobile web development.
