## 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>.

    testString: 'assert(($("#target3").hasClass("fadeOut") || $("#target3").hasClass("fadeout"))  && code.match(/\$\(\s*.#target3.\s*\)/g), ''Target the element with the id <code>target3</code> and use the jQuery <code>addClass&#40&#41</code> function to give it the class <code>fadeOut</code>.'');'
  - text: Only use jQuery to add these classes to the element.
    testString: 'assert(!code.match(/class.*animated/g), ''Only use jQuery to add these classes to the element.'');'
