## 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.

    testString: 'assert($(".btn-default").length === 0, "Remove the <code>btn-default</code> class from all of your <code>button</code> elements.");'
  - text: Only use jQuery to remove this class from the element.
    testString: 'assert(code.match(/btn btn-default/g), "Only use jQuery to remove this class from the element.");'
  - text: Only remove the <code>btn-default</code> class.
    testString: 'assert(code.match(/\.[\v\s]*removeClass[\s\v]*\([\s\v]*("|")\s*btn-default\s*("|")[\s\v]*\)/gm), "Only remove the <code>btn-default</code> class.");'
