yepnope.js | A Conditional Loader For Your Polyfills!

CSS load callbacks were taken out by default and put in an official plugin. Too few people used it. Old code will still work, callbacks will just fire immediately on CSS (unless css load plugin is included). While you can still set up your own labels for resource callbacks, yepnope now automatically creates keys for you, derived from the basename of the resource. For example, if you were loading https://my-cdn.com/jquery-ui.min.js? http://yepnopejs.com/

HTML5 Cross Browser Polyfills - GitHub

https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-browser-Polyfills Units is a JavaScript library for converting between angle and length units (including the 'rem' unit). Both are intended for use within other libraries that need to convert between acceptable CSS units when creating polyfills.

http://www.modernizr.com/ Taking advantage of the new capabilities of HTML5 and CSS3 can mean sacrificing control over the experience in older browsers. Modernizr 2 is your starting point for making the best websites and applications that work exactly right no matter what browser or device your visitors use. Thanks to the new Media Query tests and built-in YepNope.js micro-library as Modernizr.load() , you can now combine feature detection with media queries and conditional resource loading. That gives you the power and flexibility to optimize for every circumstance.
Note: Only supported in IE6 and IE7 on elements with a display of "inline" by default. Alternative properties are available to provide complete cross-browser support. Note: IE7 does not support "inherit" as a value on any of these properties. IE8 has some bugs with max-width/height combined with overflow: auto/scroll. http://caniuse.com/#
