As to your question, I’m not sure what the problem is. You haven’t written any JQuery. Acording to the instructions, you need to:
- Using .addClass(), add only one class at a time to the same element, three different ways:
- Add the animated class to all elements with type button.
- Add the shake class to all the buttons with class .btn.
- Add the btn-primary class to the button with id #target1.
All of that will be inside the
$(document).ready(function() function at the top. Please try to do it (using the examples from the problem) and then if you still have problems, let us know and we’ll be happy to help. If you have a specific question, please let us know.
