The Document Object Model (DOM) provides a representation for web pages as structured documents with a tree-like format. Each node in the tree is tied to properties, methods, and event handlers. The web page is itself referred to as the document object and can be accessed from the window object using window.document. The HTML elements on the page become element nodes such as a head element or body element. These nodes, in turn, can have children nodes such as table, div, input, and so on. Some nodes may be text nodes while some may also be comment nodes.

It is important to note that the DOM is not a programming language but rather an object-oriented model that can be used across various languages, such as JavaScript, HTML, and XML. Thus, it is language-independent and provides a common Application Programming Interface (API) that can be implemented by various languages. By connecting web pages to programming languages, you can manipulate their style, structure, and content...
