At its core, DOM manipulation is all about changing the content and appearance of a webpage in response to user interactions. From updating text, changing styles, and creating or deleting elements to handling events, DOM manipulation gives you the power to make your websites more responsive and engaging.
What Can You Do With DOM Manipulation?
DOM manipulation lets you change the content and style of your website in real time, in response to user action or data from external APIs. You can change text content, classes, styles, and so on.
The DOM can be used in HTML documents to:
- change the contents of HTML elements
- change the CSS styles of HTML elements
- add and delete HTML elements (class names)
- create new HTML elements in the web page
- insert child elements at different places in the DOM tree
Why Do DOM Manipulation?
DOM manipulation allows you to create dynamic, interactive, and responsive experiences for website users.
You can use DOM manipulation to create animation, build interactive forms, validate user input, change CSS styles in real time, and develop engaging user interfaces that respond to user actions.
Tutorials for Learning DOM Manipulation
Before taking a deep dive into DOM manipulation, I recommend starting with this highly informative overview of the DOM API:
Dynamically manipulating the DOM is a fundamental aspect of web development in creating interactive and functional web applications. The
innerHTML property is commonly used to modify the DOM, but it has some drawbacks.
This article will examine the downsides of using
innerHTML and provide some alternative approaches that can avoid these potential problems.

A webpage consists of a variety of HTML elements which are created using different tags. Some common tags include the
<html> tag, which represents the root of an HTML document, the
<body> tag, which represents the content of the document, the
p tag, which represents paragraphs, and so on.
Different tags that you use to create a webpage can also have different attributes attached to them. These attributes will either change the appearance or behavior of the elements or provide additional metadata. Some examples of attributes include
In this tutorial, we will learn how to manipulate different attributes of any element on a webpage.
Any kind of DOM manipulation first requires you to select the DOM elements that you want to manipulate. There are quite a few methods that you can use to get access to any element in your DOM. In this tutorial, we will learn how to use these methods.
In some projects you will need to add a class to all the siblings of an element if one of the siblings has that class. Or perhaps you want to show a popup if an ancestor of the current element has a specific class.
Traversing up, down, or sideways in a DOM becomes important in a lot of situations when you are doing web development.
This article gives some tips you can use to improve performance and reduce the risk of errors or bugs when manipulating the DOM.
