Click the button to remove a class from me!

Remove Class

Step 1) Add HTML:

In this example, we will use a button to remove the "mystyle" class from the <div> element with id="myDIV":


<button onclick="myFunction()">Try it</button>

<div id="myDIV" class="mystyle">
  This is a DIV element.

Step 2) Add CSS:

Style the specified class name:


.mystyle {
    width: 100%;
    padding: 25px;
    background-color: coral;
    color: white;
    font-size: 25px;

Step 3) Add JavaScript:

Get the <div> element with id="myDIV" and remove the "mystyle" class from it:


function myFunction() {
    var element = document.getElementById("myDIV");
Try it Yourself »

Cross-browser solution

Note: The classList property is not supported in Internet Explorer 9. The following code will work in all browsers:


function myFunction() {
    var element = document.getElementById("myDIV");
    element.className = element.className.replace(/\bmystyle\b/g, "");
