4632N/A <p>This demonstrates how to animate the <code>opacity</code> of an element.</p>

4632N/A <p> Click the X in the header to fade out the element.</p>

4632N/A<h2>Setting up the HTML</h2>

4632N/A<p>First we add some HTML to animate.</p>

4632N/A

4632N/A```

4632N/A{{>basic-source-html}}

4632N/A```

4632N/A<h2>Creating the Anim Instance</h2>

4632N/A<p>Now we create an instance of <code>Y.Anim</code>, passing it a configuration object that includes the <code>node</code> we wish to animate and the <code>to</code> attribute containing the final properties and their values.</p>

4632N/A

4632N/A```

4632N/Avar anim = new Y.Anim({

4632N/A node: '#demo',

4632N/A to: { opacity: 0 }

});

```

<h2>Handling the Click Event</h2>

<p>Clicking the toggle control should start the animation, so we'll need to handle that click, including preventing the default action of following the url.</p>

```

var onClick = function(e) {

e.preventDefault();

anim.run();

};

```

<h2>Running the Animation</h2>

<p>Finally we add an event listener to run the animation.</p>

```

Y.one('#demo .yui3-remove').on('click', onClick);

```

<h2>Complete Example Source</h2>

```
