An Introduction to the Document Object Model (DOM): Understanding its Structure and Functionality

 What is DOM ?

The DOM (Document Object Model) is a programming interface for HTML and XML documents. It represents the structure of a document as a tree of nodes, where each node represents an element, attribute, or text content. The DOM allows you to manipulate the content and structure of a document, add, delete or modify elements, and respond to events triggered by user actions or the system.

For example, using the DOM you can access elements in an HTML document, change their styles, text content, or attributes, and respond to events like clicks or form submissions. This makes the DOM an essential tool for building dynamic and interactive web applications.

The DOM is supported by all modern web browsers and is often used with JavaScript to create dynamic and interactive web pages.
