MooTools: Fade out element?

Question

I have an Element object that I'm currently calling .hide() on. Instead, I'd like to fade out the opacity of the entire Element (and its children) to 100% (hidden) as a transition effect over maybe 500 ms or 1000 ms.

Can Fx.Tween be used for this? Is this possible--does the MooTools framework have an effect like this in its UI library?

Answer 1

 $('myElement').fade(0.7);

sets the element opacity to 70%. Or

$('myElement').fade('out'); // fades the element out.
