## Description
|
|
<section id='description'>
|
|
You see how we made all of your <code>button</code> elements bounce? We selected them with <code>$("button")</code>, then we added some CSS classes to them with <code>.addClass("animated bounce");</code>.
|
|
You just used jQuery's <code>.addClass()</code> function, which allows you to add classes to elements.
|
|
First, let's target your <code>div</code> elements with the class <code>well</code> by using the <code>$(".well")</code> selector.
|
|
Note that, just like with CSS declarations, you type a <code>.</code> before the class's name.
|
|
Then use jQuery's <code>.addClass()</code> function to add the classes <code>animated</code> and <code>shake</code>.
|
|
For example, you could make all the elements with the class <code>text-primary</code> shake by adding the following to your <code>document ready function</code>:
|
|
<code>$(".text-primary").addClass("animated shake");</code>
