[![Build Status](https://travis-ci.org/cssinjs/css-vendor.svg?branch=master)](https://travis-ci.org/cssinjs/css-vendor) [![Greenkeeper badge](https://badges.greenkeeper.io/cssinjs/css-vendor.svg)](https://greenkeeper.io/) ## CSS vendor prefix detection and property feature testing. ### Vendor prefixes ```javascript console.log(cssVendor.prefix.js) // e.g. WebkitTransform console.log(cssVendor.prefix.css) // e.g. -webkit-transform ``` ### Property support feature test `cssVendor.supportedProperty(prop)` Test if property is supported, returns false if not. Returns string if supported. May add a vendor prefix if needed. ```javascript console.log(cssVendor.supportedProperty('animation')) // e.g. -webkit-animation ``` ### Value support feature test `cssVendor.supportedValue(prop, value)` Test if value is supported, returns false if not. Returns string if supported. May add a vendor prefix if needed. ```javascript console.log(cssVendor.supportedValue('display', 'flex')) // e.g. -webkit-flex ``` ## Run tests ```bash yarn yarn test ``` ## License MIT
