## Description
<section id='description'>
Now you know three ways of targeting elements: by type: <code>$("button")</code>, by class: <code>$(".btn")</code>, and by id <code>$("#target1")</code>.
Although it is possible to add multiple classes in a single <code>.addClass()</code> call, let's add them to the same element in <em>three separate ways</em>.
Using <code>.addClass()</code>, add only one class at a time to the same element, three different ways:
Add the <code>animated</code> class to all elements with type <code>button</code>.
Add the <code>shake</code> class to all the buttons with class <code>.btn</code>.
Add the <code>btn-primary</code> class to the button with id <code>#target1</code>.
<strong>Note</strong><br>You should only be targeting one element and adding only one class at a time. Altogether, your three individual selectors will end up adding the three classes <code>shake</code>, <code>animated</code>, and <code>btn-primary</code> to <code>#target1</code>.

    testString: 'assert(code.match(/\$\s*?\(\s*?(?:"|")\s*?#target1\s*?(?:"|")/gi), "Use the <code>$&#40"#target1"&#41</code> selector.");'
  - text: Only add one class with each of your three selectors.
    testString: 'assert(code.match(/addClass/g) && code.match(/addClass\s*?\(\s*?("|")\s*?[\w-]+\s*?\1\s*?\)/g).length > 2, "Only add one class with each of your three selectors.");'
  - text: 'Your <code>#target1</code> element should have the classes <code>animated</code>&#130; <code>shake</code> and <code>btn-primary</code>.'
    testString: 'assert($("#target1").hasClass("animated") && $("#target1").hasClass("shake") && $("#target1").hasClass("btn-primary"), "Your <code>#target1</code> element should have the classes <code>animated</code>&#130; <code>shake</code> and <code>btn-primary</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.");'
