Basics of DOM
Learn the basics of the DOM, its interaction with HTML, and how to navigate its hierarchy.
The DOM (Document Object Model) is a programming interface that represents the structure of an HTML or XML document as a tree-like hierarchy. Each element, attribute, and piece of text in the document is represented as a node, enabling JavaScript to interact with and manipulate the document programmatically.
Relationship between HTML and the DOM
HTML provides the static structure of a web page, but the DOM acts as its live representation. When a browser loads an HTML document, it parses the content into the DOM, which allows JavaScript to dynamically update the page’s content and structure.
Browser as an interpreter of the DOM
Browsers read the HTML file, convert it into the DOM, and render the visual web page based on the DOM. Any changes made to the DOM via JavaScript immediately reflect on the web page, creating an interactive experience for users.
