CSS Transitions and Javascript

If you are using CSS Transitions and want to provide Javascript equivalents to user agents that do not support them, this may help you:

function isCSSAnimCapable() {
    return (
        ("WebkitTransition" in document.documentElement.style) ||
        ("MozTransition" in document.documentElement.style) ||
        ("MsTransition" in document.documentElement.style) ||
        ("OTransition" in document.documentElement.style) ||
        ("Transition" in document.documentElement.style)
    );
}

It does however become a little messy trying to do animation from both Javascript and CSS. You have been warned.
