Fx.CSS3

Mimics the Fx behavior but tries to use native CSS3 transition if possible. Like the Fx effect, Fx.CSS3 is used to transition any CSS property from one value to another.

Demos:

• You can see a simple online demo in this shell
• More complex demo: SqueezeBox using Fx.Tween.CSS3

Options, Events:

See: FX.Tween

Notes:

Only short notated transitions are supported as option.transition by Fx.Tween.CSS3. Like:

new Fx.Tween.CSS3('myElementID', {
	
	transition: 'sine:in'
	
});

Performance:

Tested on OSX 10.6:

• Safari 4: 30% faster than Fx.Tween
• Google Chrome 5: nearly equal compared to Fx.Tween
• Firefox 3.6.3: nearly equal compared to Fx.Tween
• Opera 10.53: nearly equal compared to Fx.Tween

Tested on iPhone 3GS:

• Mobile Safari: runns a lot faster (and smoother) than Fx.Tween (with default fps)

Tested on Windows 7:

• Safari 4: a lot faster than Fx.Tween (200 running instances of Fx.Tween hangs the browser, 200 Fx.Tween.CSS3 instances still working (40% CPU usage))
• Google Chrome 5: 50% faster than Fx.Tween
• Firefox 3.6.3: nearly equal compared to Fx.Tween
• Opera 10.53: nearly equal compared to Fx.Tween

How to use

window.addEvent('domready', function(){
	
    var fx = new Fx.Tween.CSS3('myElementID', {
        duration: 605,
        transition: 'quint:in:out'
    });

    fx.addEvent('complete', function(){
        alert('complete');
    });
		
    fx.start('height', 100, 300);

});
