Document Object model, referred to as the DOM.

• DOM is the standard of the World Wide Web Consortium and is a rule.
• The Dom defines the standard rules for accessing and manipulating HTML and XML content, like the VIP card we use to cut our hair, and the barber shop rules that only members can enjoy the offer, which is a standard, and the barber's rules are similar to the DOM, The content of the offer is like HTML or XML content in general, and only from this provision can the content be correctly accessed.
• In the HTML DOM , all the elements are considered nodes, the entire HTML document as a node tree, and then using the standard methods defined in the Dom to access these nodes, which is actually the role of Dom , will the content of the HTML document is converted to a node form for easy access and use.

The following is an example of an HTML DOM node tree

with the concept of this node tree, we can use the DOM standard to access all node content in the node tree using the JavaScript language. All HTML element content is considered an object, and the object's properties and methods are the programming interface

• getElementById () method
