Hide element by class using JavaScript

In this tutorial, we are going to learn about how to hide an element by class using JavaScript.

Consider, we have a following html div element.

<div class="box">Hello</div>

To hide an element, first we need to access it inside the JavaScript using the document.getElementsbyClassName() then set its style.display property to none.

Here is an example:

const element = document.getElementsbyClassName("box");

element.style.display= "none";

Using style.visibility property

Similarly, we can also hide an element by specific class using the element’s style.visibility property.

Here is an example:

const element = document.getElementsbyClassName("container");
element.style.visibility= "hidden";

In the example above:

First, we have accessed the html element using the document.getElementsbyClassName() method then we updated the element’s style.visibility property to hidden. so it hides the element from a dom.

The main difference between style.display and style.visibility properties are:

• When we set a style.display property to none, it removes the element completely from the dom .

• When we set a style.display property to hidden, it just hides the element but doesn’t remove it in the dom.
