## Description
< section id = 'description' >
In the same way you can add classes to an element with jQuery's < code > addClass()< / code > function, you can remove them with jQuery's < code > removeClass()< / code > function.
Here's how you would do this for a specific button:
< code > $("#target2").removeClass("btn-default");< / code >
Let's remove the < code > btn-default< / code > class from all of our < code > button< / code > elements.
