It also includes many basic DOM element manipulations, fallbacks and polyfills as well as integration with Apache Cordova (including PhoneGap) and so on.
CrossBrowdy focuses on cross-browser (including legacy browsers) and cross-platform compatibility. The main target is to allow any app to run in any browser with or without HTML5 compatibility.
