The .removeClass() method allows you to remove a class name from the specified element. If you want to remove more than one class name you just separate each class name with a space.

$(".insetPP").removeClass("boldIt"); // this will remove the class name of boldIt from the element with class="insetPP"

<div class="insetPP boldIt">
    <p>The Title of the Book</p>
    <p>This is a very interesting work of literature</p>

When you use .removeClass() it will not affect the element if the class does not already exist. If you just want to change some aspect, color, background, etc., you can also use .css(). The .css() method will add inline styling to the element. Inline styling can not be overwritten with stylesheet styling.

The opposite of .removeClass() is .addClass().
