Document Object Model

The DOM standard specifies a few interfaces (think: objects) and mixins that allow a programming language (usually JavaScript) to manipulate the elements that are stored in a DOM tree.

These interfaces are:

• AbortController
• AbortSignal
• AbstractRange
• Attr
• CDATASection
• CharacterData
• Comment
• CustomEvent
• Document (which is significantly extended by the Document interface of HTML)
• DocumentFragment
• DocumentType
• DOMImplementation
• DOMTokenList
• Element (from which objects correspdonding to HTML elements such as HTMLElement, HTMLDivElement, HTMLBodyElement etc. interfaces inherit)
• Event
• EventTarget (implemented by objects that can receive events and may have listeners for them).
• HTMLCollection
• NamedNodeMap
• Node
• NodeFilter
• NodeIterator
• NodeList
• MutationObserver
• MutationRecord
• ProcessingInstruction
• Range
• ShadowRoot
• StaticRange
• Text
• TreeWalker
• XPathEvaluator
• XPathExpression
• XPathResult

The mixins are

• ChildNode
• DocumentOrShadowRoot
• NonDocumentTypeChildNode
• NonElementParentNode
• ParentNode
• Slotable
• XPathEvaluatorBase

These interfaces and mixins are described with Web IDL.

On 28 May 2019, the W3C announced that WHATWG would be the sole publisher of the HTML and DOM standards.
