<p>This demonstrates how to animate the <code>opacity</code> of an element.</p>
<p> Click the X in the header to fade out the element.</p>

<div class="yui3-hd">
<h3>Basic Animation</h3>
<a href="remove.php?id=#demo" title="fade out element" class="yui3-remove"><em>x</em></a>
</div>
<div class="yui3-bd">
<p>Click the X in the header to fade out the element.</p>
</div>
</div>
<script type="text/javascript">
YUI().use('anim', function(Y) {
var anim = new Y.Anim({
node: '#demo',
to: { opacity: 0 }
});
var onClick = function(e) {
e.preventDefault();
anim.run();
};
Y.one('#demo .yui3-remove').on('click', onClick);
});
</script>
</div>
<h2>Setting up the HTML</h2>
<p>First we add some HTML to animate.</p>
<pre class="code prettyprint"><div id="demo" class="yui3-module">
<div class="yui3-hd">
<h3>Basic Animation</h3>
<a href="remove.php?id=#demo" title="fade out element" class="yui3-remove"><em>x</em></a>
</div>
<div class="yui3-bd">
<p>Click the X in the header to fade out the element.</p>
</div>
</div></pre>
<h2>Creating the Anim Instance</h2>
<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>
<pre class="code prettyprint">var anim = new Y.Anim({
node: '#demo',
to: { opacity: 0 }
});</pre>
<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>
<pre class="code prettyprint">var onClick = function(e) {
e.preventDefault();
anim.run();
};</pre>
<h2>Running the Animation</h2>
<p>Finally we add an event listener to run the animation.</p>
<pre class="code prettyprint">Y.one('#demo .yui3-remove').on('click', onClick);</pre>
