Remove a Class from an Element

To remove a class from an element, you use the remove() method of the classList property of the element.

Suppose you have a <div> element as follows:

<div class="primary visible info">Item</div>

To remove the visible class from the div element, you use the following code:

const div =  document.querySelector('div');
div.classList.remove('info');

The remove() method also allows you to remove multiple classes at once, like this:

const div = document.querySelector('div');
div.classList.remove('info','primary');
