Target HTML Elements with Selectors Using jQuery

Now we have a document ready function.

Now let's write our first jQuery statement. All jQuery functions start with a $, usually referred to as a dollar sign operator, or as bling.

jQuery often selects an HTML element with a selector, then does something to that element.

For example, let's make all of your button elements bounce. Just add this code inside your document ready function:

$("button").addClass("animated bounce");

Note that we've already included both the jQuery library and the Animate.css library in the background so that you can use them in the editor. So you are using jQuery to apply the Animate.css bounce class to your button elements.

Additionally make sure to use $("button").addClass("animated bounce"); instead of $('button').addClass("animated bounce"); since single-quote selectors will not pass our tests.

Use the jQuery addClass() function to give the classes animated and bounce to your button elements.

Only use jQuery to add these classes to the element.

Only use double quotes in your jQuery code, as is stated in the jQuery style guide.

<script>
  $(document).ready(function() {
  });
