Adding a Class to a DOM Element: A Quick Guide

Tags: DOM manipulation, add class, remove class

If you need to add a class to a DOM element, it can be easily achieved by using the add() method provided by the classList property. This article will walk you through the process step by step.

When you have a reference to a DOM element, you can simply call the add() method on its classList property, like this:

element.classList.add('myclass');

This line of code will add the class myclass to the specified DOM element.

Similarly, if you want to remove a class, you can utilize the remove() method:

element.classList.remove('myclass');

Keep in mind that classList is not an array but a collection of type DOMTokenList. Although it is not directly editable, you can leverage its methods to manipulate the element’s classes.

By following these simple steps, you can easily add or remove classes from any DOM element. Happy coding!
