How to detect CSS features

If we want to detect whether a CSS property supports

var dom = document.createelement (' P '), if (' Textshadow ' in Dom.style) {    alert (' Support Textshadow attribute ')}else {    alert (' Textshadow attribute ' not supported ')}

If we want to detect if the CSS3 property supports a value

var dom = document.createelement (' P ');d om.style.backgroundImage = ' linear-gradient (red, tan) '; Dom.style.backgroundImage) {    alert (' supports this attribute value ');} else {    alert (' Browser does not support this property value ')}

How to dynamically assign a CSS3 effect and support all major browsers

function Islider () {};/** * @returns {String} * @private */islider.transition_end_event = Null;islider.browser_prefix = Nu    ll; (function () {var e = document.createelement (' fakeelement '); [[' Webkittransition ', ' webkittransitionend ', ' WebKit '], [' transition ', ' transitionend ', null], [' Moz Transition ', ' transitionend ', ' Moz '], [' otransition ', ' otransitionend ', ' O ']].some (function (t) {if (E.
