The Document Object Model (DOM) in the context of web browsers refers to a programming interface for HTML and XML documents. It represents the document as an object tree, allowing developers to interact with its elements and manipulate their properties or attributes, change their content, style them, etc., in response to user events. This is often done using JavaScript code within the browser environment. The DOM allows for dynamic and interactive web pages and applications that can respond to user actions in real time, making it a fundamental technology behind modern websites and web applications.
