Fx.Elements allows you to apply any number of styles transitions to a collection of Elements.

• Fx

new Fx.Elements(elements[, options]);

1. elements - (array) A collection of Elements the effects will be applied to.
2. options - (object, optional) Same as Fx options.

• (object) A new Fx.Elements instance.

var myFx = new Fx.Elements($$('.myElementClass'), {
    onComplete: function(){
        alert('complete');
    }
}).start({
    0: {
        height: [200, 300],
        opacity: [0,1]
    },
    1: {
        width: [200, 300],
        opacity: [1,0]
    }
});

• Includes colors but must be in hex format.

Applies the passed in style transitions to each object named immediately (see example).

myFx.set(to);

1. to - (object) An object where each item in the collection is refered to as a numerical string ("1" for instance). The first item is "0", the second "1", etc.

• (object) This Fx.Elements instance.

var myFx = new Fx.Elements($$('.myClass')).set({
    '0': {
        'height': 200,
        'opacity': 0
    },
    '1': {
        'width': 300,
        'opacity': 1
    }
});

Applies the passed in style transitions to each object named (see example).

var myElementsEffects = new Fx.Elements($$('a'));
myElementsEffects.start({
    '0': { //let's change the first element's opacity and width

        'width': [100,200]
    },
    '4': { //and the fifth one's opacity
