Using the jQuery removeClass() method deletes one or more specified classes in the selected HTML elements. It can also be used in XML language.
Syntax:

$(“selector”).removeClass(“className_to_remove”);

By combining the addClass() and removeClass() methods, it is possible to replace the classes wich assigned to the elements.











Example how remove(deletes) multiple clasess to elements with onclick button function

code:


<!DOCTYPE html>
<html>
 <head>
  <title>IT PRESENT</title>
  <style>
.a {
background-image: url("images/honeycomb.jpg");
}
.b {

.d {
