Allows for the animation of multiple CSS properties at once, even by a CSS selector. Inherits methods, properties, options and events from Fx.

• Fx

var myFx = new Fx.Morph(element[, options]);

1. element - (mixed) A string ID of the Element or an Element to apply the style transitions to.
2. options - (object, optional) The Fx options object.

• (object) A new Fx.Morph instance.

Multiple styles with start and end values using an object:

var myEffect = new Fx.Morph('myElement', {
    duration: 'long',
    transition: Fx.Transitions.Sine.easeOut
});

myEffect.start({
    'height': [10, 100], // Morphs the 'height' style from 10px to 100px.
    'width': [900, 300]  // Morphs the 'width' style from 900px to 300px.
});

Multiple styles with the start value omitted will default to the current Element's value:

var myEffect = new Fx.Morph('myElement', {
    duration: 'short',
    transition: Fx.Transitions.Sine.easeOut
});

myEffect.start({
    'height': 100, // Morphs the height from the current to 100px.
    'width': 300   // Morphs the width from the current to 300px.
});

Morphing one Element to match the CSS values within a CSS class. This is useful when separating the logic and styles:

var myEffect = new Fx.Morph('myElement', {
    duration: 1000,
    transition: Fx.Transitions.Sine.easeOut
});

// the styles of myClassName will be applied to the target Element.
myEffect.start('.myClassName');

• Fx

Sets the Element's CSS properties to the specified values immediately.

myFx.set(to);

1. properties - (mixed) Either an object of key/value pairs of CSS attributes to change or a string representing a CSS selector which can be found within the CSS of the page. If only one value is given for any CSS property, the transition will be from the current value of that property to the value given.

• (object) This Fx.Morph instance.

var myFx = new Fx.Morph('myElement').set({
    'height': 200,
    'width': 200,
    'background-color': '#f00',
    'opacity': 0
});
var myFx = new Fx.Morph('myElement').set('.myClass');

Executes a transition for any number of CSS properties in tandem.

myFx.start(properties);

1. properties - (mixed) An object of key/value pairs of CSS attributes to change or a string representing a CSS selector which can be found within the CSS of the page. If only one value is given for any CSS property, the transition will be from the current value of that property to the value given.

• (object) This Fx.Morph instance.

var myEffects = new Fx.Morph('myElement', {duration: 1000, transition: Fx.Transitions.Sine.easeOut});

myEffects.start({
    'height': [10, 100],
    'width': [900, 300],
    'opacity': 0,
    'background-color': '#00f'
});

• If a string is passed as the CSS selector, the selector must be identical to the one within the CSS.
• Multiple selectors (with commas) are not supported.

see Element.Properties

Sets a default Fx.Morph instance for an Element.

el.set('morph'[, options]);

1. options - (object, optional) The Fx.Morph options.

• (element) This Element.

el.set('morph', {duration: 'long', transition: 'bounce:out'});
el.morph({height: 100, width: 100});

Gets the default Fx.Morph instance for the Element.

el.get('morph');

1. property - (string) the Fx.Morph property argument.

• (object) The Fx.Morph instance.

el.set('morph', {duration: 'long', transition: 'bounce:out'});
el.morph({height: 100, width: 100});
el.get('morph'); // the Fx.Morph instance.

Animates an Element given the properties passed in.

myElement.morph(properties);

1. properties - (mixed) The CSS properties to animate. Can be either an object of CSS properties or a string representing a CSS selector. If only one value is given for any CSS property, the transition will be from the current value of that property to the value given.

• (element) This Element.

With an object:

$('myElement').morph({height: 100, width: 200});

With a selector:

$('myElement').morph('.class1');
