What is DOM processing?
DOM processing is the time it takes to parse the HTML into a DOM and retrieve or execute synchronous scripts. If the browser starts to download images in this phase, page load timing will capture the image load time.

What is DOM in HTML?
In this post, we will discuss Document Object Model (DOM) along with its properties and methods used to manipulate Document.#N#Introduction :#N#The Document Object Model (DOM) is a programming interface for HTML and XML (Extensible markup language) documents. It defines the logical structure of documents and the way a document is accessed and manipulated.#N#Note: It is called a Logical structure because DOM doesn’t specify any relationship between objects.#N#DOM is a way to represent the webpage in a structured hierarchical way so that it will become easier for programmers and users to glide through the document. With DOM, we can easily access and manipulate tags, IDs, classes, Attributes, or Elements using commands or methods provided by the Document object.#N#Structure of DOM:#N#DOM can be thought of as a Tree or Forest (more than one tree). The term structure model is sometimes used to describe the tree-like representation of a document. One important property of DOM structure models is structural isomorphism: if any two DOM implementations are used to create a representation of the same document, they will create the same structure model, with precisely the same objects and relationships.#N#Why called an Object Model?#N#Documents are modeled using objects, and the model includes not only the structure of a document but also the behavior of a document and the objects of which it is composed of like tag elements with attributes in HTML.#N#Properties of DOM:#N#Let’s see the properties of the document object that can be accessed and modified by the document object.
What is not a DOM?
What DOM is not? The Document Object Model is not a binary description where it does not define any binary source code in its interfaces. The Document Object Model is not used to describe objects in XML or HTML whereas the DOM describes XML and HTML documents as objects.
Why is DOM called a logical structure?
Note: It is called a Logical structure because DOM doesn’t specify any relationship between objects. DOM is a way to represent the webpage in a structured hierarchical way so that it will become easier for programmers and users to glide through the document.
