I don't know how to set the values for browser specific css styles.

But take a look at this library: http://rekapi.com/
It may be what you need.

Coding KeyFrames manually for each browser would be a big headache, if you can use something that is ready, use it.

Hope it helps.

you can create a style tag, my sample's placed on the head. Then from there write the keyframe rules. like this:

var styleSheetElement = document.createElement("style"), customStyleSheet;

document.head.appendChild(styleSheetElement);

// get the appended stylesheet
// you can use the returned node from the appendage like this
// customStyleSheet = (document.head.appendChild(styleSheetElement)).sheet
customStyleSheet = document.styleSheets[0];

// Make sure you apply the appropriate css rule name for the browser, as
// "@keyframes" the standard while different browser has their own rule name
// example, if you're using Chrome you should use "@-webkit-keyframes" instead.
// the browser will throw an error if you provided the wrong css rule name
customStyleSheet.insertRule("@keyframes myfirst { from {height:188px; } to {height:10px;}}");

By the way, I'd go with AleMontiero, coding for different browsers a big headache. It's gonna blow your head off. LOL
I really don't know why they can't get into harmony.

Asside from the CSSRule, I really don't know what you mean by this

Can you provide your code in JSFiddle, to check where the problem was.
