## Description
<section id='description'>
You can also target elements by their id attributes.
First target your <code>button</code> element with the id <code>target3</code> by using the <code>$("#target3")</code> selector.
Note that, just like with CSS declarations, you type a <code>#</code> before the id's name.
Then use jQuery's <code>.addClass()</code> function to add the classes <code>animated</code> and <code>fadeOut</code>.
Here's how you'd make the <code>button</code> element with the id <code>target6</code> fade out:
<code>$("#target6").addClass("animated fadeOut")</code>.

- text: Only use jQuery to add these classes to the element.
