A document, in turn, consists of a hierarchical tree of <strong>nodes</strong>, in which a node is a fundamental record representing a single object within the document (such as an element or text node).</p> <p>Nodes may be strictly organizational, providing a means for grouping other nodes together or for providing a point at which a hierarchy can be constructed; other nodes may represent visible components of a document. Each node is based on the <a href="/en-US/docs/Web/API/Node"><code>Node</code></a> interface, which provides properties for getting information about the node as well as methods for creating, deleting, and organizing nodes within the DOM.</p> <p>Nodes don't have any concept of including the content that is actually displayed in the document. They're empty vessels. The fundamental notion of a node that can represent visual content is introduced by the <a href="/en-US/docs/Web/API/Element"><code>Element</code></a> interface. An <code>Element</code> object instance represents a single element in a document created using either HTML or an <a href="/en-US/docs/Glossary/XML">XML</a> vocabulary such as <a href="/en-US/docs/Glossary/SVG">SVG</a>.</p> <p>For example, consider a document with two elements, one of which has two more elements nested inside it:</p> <p> <img src="/en-US/docs/Web/API/HTML_DOM_API/dom-structure.svg" alt="Structure of a document with elements inside a document in a window" width="291" height="379" loading="lazy"> </p> <p>While the <a href="/en-US/docs/Web/API/Document"><code>Document</code></a> interface is defined as part of the <a href="/en-US/docs/Web/API/Document_Object_Model" title="DOM">DOM</a> specification, the HTML specification significantly enhances it to add information specific to using the DOM in the context of a web browser, as well as to using it to represent HTML documents specifically.</p> <p>Among the things added to <code>Document</code> by the HTML standard are:</p> <ul> <li>Support for accessing various information provided by the <a href="/en-US/docs/Glossary/HTTP">HTTP</a> headers when loading the page, such as the <a href="/en-US/docs/Web/API/Document/location" title="location">location</a> from which the document was loaded, <a href="/en-US/docs/Web/API/Document/cookie" title="cookies">cookies</a>, <a href="/en-US/docs/Web/API/Document/lastModified" title="modification date">modification date</a>, <a href="/en-US/docs/Web/API/Document/referrer" title="referring site">referring site</a>, and so forth.</li> <li>Access to lists of elements in the document's <a href="/en-US/docs/Web/HTML/Element/head"><code><head></code></a> block and <a href="/en-US/docs/Web/API/Document/body" title="body">body</a>, as well as lists of the <a href="/en-US/docs/Web/API/Document/images" title="images">images</a>, <a href="/en-US/docs/Web/API/Document/links" title="links">links</a>, <a href="/en-US/docs/Web/API/Document/scripts" title="scripts">scripts</a>, etc. contained in the document.</li> <li>Support for interacting with the user by examining <a href="/en-US/docs/Web/API/Document/hasFocus" title="focus">focus</a> and by executing commands on <a href="/en-US/docs/Web/HTML/Global_attributes/contenteditable">editable content</a>.</li> <li>Event handlers for document events defined by the HTML standard to allow access to <a href="/en-US/docs/Web/API/MouseEvent" title="mouse">mouse</a> and <a href="/en-US/docs/Web/API/KeyboardEvent" title="keyboard">keyboard</a> events, <a href="/en-US/docs/Web/API/HTML_Drag_and_Drop_API" title="drag and drop">drag and drop</a>, <a href="/en-US/docs/Web/API/HTMLMediaElement" title="media control">media control</a>, and more.</li> <li>Event handlers for events that can be delivered to both elements and documents; these presently include only <a href="/en-US/docs/Web/API/HTMLElement/copy_event" title="copy">copy</a>, <a href="/en-US/docs/Web/API/HTMLElement/cut_event" title="cut">cut</a>, and <a href="/en-US/docs/Web/API/HTMLElement/paste_event" title="paste">paste</a> actions.</li> </ul></div></section><section aria-labelledby="html_element_interfaces"><h3 id="html_element_interfaces"><a href="#html_element_interfaces">HTML element interfaces</a></h3><div class="section-content"><p>The <code>Element</code> interface has been further adapted to represent HTML elements specifically by introducing the <a href="/en-US/docs/Web/API/HTMLElement"><code>HTMLElement</code></a> interface, which all more specific HTML element classes inherit from. This expands the <code>Element</code> class to add HTML-specific general features to the element nodes. Properties added by <code>HTMLElement</code> include for example <a href="/en-US/docs/Web/API/HTMLElement/hidden" title="hidden"><code>hidden</code></a> and <a href="/en-US/docs/Web/API/HTMLElement/innerText" title="innerText"><code>innerText</code></a>.</p> <p>An <a href="/en-US/docs/Glossary/HTML">HTML</a> document is a DOM tree in which each of the nodes is an HTML element, represented by the <a href="/en-US/docs/Web/API/HTMLElement"><code>HTMLElement</code></a> interface. The <code>HTMLElement</code> class, in turn, implements <code>Node</code>, so every element is also a node (but not the other way around). This way, the structural features implemented by the <a href="/en-US/docs/Web/API/Node"><code>Node</code></a> interface are also available to HTML elements, allowing them to be nested within each other, created and deleted, moved around, and so forth.</p> <p>The <code>HTMLElement</code> interface is generic, however, providing only the functionality common to all HTML elements such as the element's ID, its coordinates, the HTML making up the element, information about scroll position, and so forth.</p> <p>In order to expand upon the functionality of the core <code>HTMLElement</code> interface to provide the features needed by a specific element, the <code>HTMLElement</code> class is subclassed to add the needed properties and methods. For example, the <a href="/en-US/docs/Web/HTML/Element/canvas"><code><canvas></code></a> element is represented by an object of type <a href="/en-US/docs/Web/API/HTMLCanvasElement"><code>HTMLCanvasElement</code></a>. <code>HTMLCanvasElement</code> augments the <code>HTMLElement</code> type by adding properties such as <a href="/en-US/docs/Web/API/HTMLCanvasElement/height" title="height"><code>height</code></a> and methods like <a href="/en-US/docs/Web/API/HTMLCanvasElement/getContext" title="getContext()"><code>getContext()</code></a> to provide canvas-specific features.</p> <p>The overall inheritance for HTML element classes looks like this:</p> <p> <img src="/en-US/docs/Web/API/HTML_DOM_API/html-dom-hierarchy.svg" alt="Hierarchy of interfaces for HTML elements" width="661" height="565" loading="lazy"> </p> <p>As such, an element inherits the properties and methods of all of its ancestors. For example, consider a <a href="/en-US/docs/Web/HTML/Element/a"><code><a></code></a> element, which is represented in the DOM by an object of type <a href="/en-US/docs/Web/API/HTMLAnchorElement"><code>HTMLAnchorElement</code></a>. The element, then, includes the anchor-specific properties and methods described in that class's documentation, but also those defined by <a href="/en-US/docs/Web/API/HTMLElement"><code>HTMLElement</code></a> and <a href="/en-US/docs/Web/API/Element"><code>Element</code></a>, as well as from <a href="/en-US/docs/Web/API/Node"><code>Node</code></a> and, finally, <a href="/en-US/docs/Web/API/EventTarget"><code>EventTarget</code></a>.</p> <p>Each level defines a key aspect of the utility of the element. From <code>Node</code>, the element inherits concepts surrounding the ability for the element to be contained by another element, and to contain other elements itself. Of special importance is what is gained by inheriting from <code>EventTarget</code>: the ability to receive and handle events such as mouse clicks, play and pause events, and so forth.</p> <p>There are elements that share commonalities and thus have an additional intermediary type. For example, the <a href="/en-US/docs/Web/HTML/Element/audio"><code><audio></code></a> and <a href="/en-US/docs/Web/HTML/Element/video"><code><video></code></a> elements both present audiovisual media. The corresponding types, <a href="/en-US/docs/Web/API/HTMLAudioElement"><code>HTMLAudioElement</code></a> and <a href="/en-US/docs/Web/API/HTMLVideoElement"><code>HTMLVideoElement</code></a>, are both based upon the common type <a href="/en-US/docs/Web/API/HTMLMediaElement"><code>HTMLMediaElement</code></a>, which in turn is based upon <a href="/en-US/docs/Web/API/HTMLElement"><code>HTMLElement</code></a> and so forth. <code>HTMLMediaElement</code> defines the methods and properties held in common between audio and video elements.</p> <p>These element-specific interfaces make up the majority of the HTML DOM API, and are the focus of this article.

This expands the <code>Element</code> class to add HTML-specific general features to the element nodes. Properties added by <code>HTMLElement</code> include for example <a href=\"/en-US/docs/Web/API/HTMLElement/hidden\" title=\"hidden\"><code>hidden</code></a> and <a href=\"/en-US/docs/Web/API/HTMLElement/innerText\" title=\"innerText\"><code>innerText</code></a>.</p>\n<p>An <a href=\"/en-US/docs/Glossary/HTML\">HTML</a> document is a DOM tree in which each of the nodes is an HTML element, represented by the <a href=\"/en-US/docs/Web/API/HTMLElement\"><code>HTMLElement</code></a> interface. The <code>HTMLElement</code> class, in turn, implements <code>Node</code>, so every element is also a node (but not the other way around). This way, the structural features implemented by the <a href=\"/en-US/docs/Web/API/Node\"><code>Node</code></a> interface are also available to HTML elements, allowing them to be nested within each other, created and deleted, moved around, and so forth.</p>\n<p>The <code>HTMLElement</code> interface is generic, however, providing only the functionality common to all HTML elements such as the element's ID, its coordinates, the HTML making up the element, information about scroll position, and so forth.</p>\n<p>In order to expand upon the functionality of the core <code>HTMLElement</code> interface to provide the features needed by a specific element, the <code>HTMLElement</code> class is subclassed to add the needed properties and methods. For example, the <a href=\"/en-US/docs/Web/HTML/Element/canvas\"><code><canvas></code></a> element is represented by an object of type <a href=\"/en-US/docs/Web/API/HTMLCanvasElement\"><code>HTMLCanvasElement</code></a>. <code>HTMLCanvasElement</code> augments the <code>HTMLElement</code> type by adding properties such as <a href=\"/en-US/docs/Web/API/HTMLCanvasElement/height\" title=\"height\"><code>height</code></a> and methods like <a href=\"/en-US/docs/Web/API/HTMLCanvasElement/getContext\" title=\"getContext()\"><code>getContext()</code></a> to provide canvas-specific features.</p>\n<p>The overall inheritance for HTML element classes looks like this:</p>\n<p>\n <img src=\"/en-US/docs/Web/API/HTML_DOM_API/html-dom-hierarchy.svg\" alt=\"Hierarchy of interfaces for HTML elements\" width=\"661\" height=\"565\" loading=\"lazy\">\n</p>\n<p>As such, an element inherits the properties and methods of all of its ancestors. For example, consider a <a href=\"/en-US/docs/Web/HTML/Element/a\"><code><a></code></a> element, which is represented in the DOM by an object of type <a href=\"/en-US/docs/Web/API/HTMLAnchorElement\"><code>HTMLAnchorElement</code></a>. The element, then, includes the anchor-specific properties and methods described in that class's documentation, but also those defined by <a href=\"/en-US/docs/Web/API/HTMLElement\"><code>HTMLElement</code></a> and <a href=\"/en-US/docs/Web/API/Element\"><code>Element</code></a>, as well as from <a href=\"/en-US/docs/Web/API/Node\"><code>Node</code></a> and, finally, <a href=\"/en-US/docs/Web/API/EventTarget\"><code>EventTarget</code></a>.</p>\n<p>Each level defines a key aspect of the utility of the element. From <code>Node</code>, the element inherits concepts surrounding the ability for the element to be contained by another element, and to contain other elements itself. Of special importance is what is gained by inheriting from <code>EventTarget</code>: the ability to receive and handle events such as mouse clicks, play and pause events, and so forth.</p>\n<p>There are elements that share commonalities and thus have an additional intermediary type. For example, the <a href=\"/en-US/docs/Web/HTML/Element/audio\"><code><audio></code></a> and <a href=\"/en-US/docs/Web/HTML/Element/video\"><code><video></code></a> elements both present audiovisual media. The corresponding types, <a href=\"/en-US/docs/Web/API/HTMLAudioElement\"><code>HTMLAudioElement</code></a> and <a href=\"/en-US/docs/Web/API/HTMLVideoElement\"><code>HTMLVideoElement</code></a>, are both based upon the common type <a href=\"/en-US/docs/Web/API/HTMLMediaElement\"><code>HTMLMediaElement</code></a>, which in turn is based upon <a href=\"/en-US/docs/Web/API/HTMLElement\"><code>HTMLElement</code></a> and so forth. <code>HTMLMediaElement</code> defines the methods and properties held in common between audio and video elements.</p>\n<p>These element-specific interfaces make up the majority of the HTML DOM API, and are the focus of this article.
