## 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>.
