List of CSS properties supported by the browsers in the wild

Why

Tools. Transpilers. Pre/post processors.

Installation

$ npm install cssprops

Browsers

The list of maintained browsers is as follows:

• IE6
• IE7
• IE8
• IE9
• IE10
• IE11
• IE (same as IE11)
• Chrome (35.0.1916.114)
• Firefox (32.0a1)
• Safari (Version 7.0.4 (9537.76.4))
• iOS Safari - latest
• Opera - latest
• Forward - merge of all non-versioned browsers

The idea of "forward" is that any feature supported in any modern browser has a shot of being supported by others eventually. This is an acceptable approximation - let's your transpiler output "future-proof" CSS.

Usage

After installation, go:

var cssprops = require('cssprops');
Array.isArray(cssprops.ie6); // true
cssprops.ie6.length; // 115
cssprops.firefox.indexOf('zoom'); // -1, no `zoom` in FF

What's available:

Object.keys(cssprops);

Result:

[ 'chrome',
  'firefox',
  'ie10',
  'ie11',
  'ie',
  'ie6',
  'ie7',
  'ie8',
  'ie9',
  'ios',
  'opera',
  'safari',
  'forward' ]

Contribute

• Run http://props.csspatterns.com/ in your browser (source is here on github)
• If you see a message, send a pull request to replace the browser file (e.g. chrome.txt) from the raw dir
• Don't worry about .js files, these are generated by the build script
• Properties rarely go away, so pull request to remove properties are unlikely
