How to use the remove( ) Method In Javascript

To remove a class name from an element with JavaScript. First style the paragraph with background color. The JavaScript function removeBackgroundColor is defined inside the <script> block. This function is triggered when the button is clicked (onclick="removeBackgroundColor()"). The remove() is called on classList to remove a specified class. It retrieves the paragraph element with the ID myParagraph and removes the class custom-background from it.
