What is the DOM?
At the most basic level, a website consists of an HTML document. The browser that you use to view the website is a program that interprets HTML and CSS and renders the style, content, and structure into the page that you see.

<html lang="en"> <head> <title>Learning the DOM</title> </head> <body> <h1>Document Object Model</h1> </body> </html>
The above is the simple HTML code, and also you might be knowing that almost all the webpages have their structure defined in HTML. Now just inspect the element on this page and see the elements tab on the right-hand side of the browser. Whenever you hover over some line you can see some effect on the webpage depicting the element you are hovering at.
You might also see the arrows in the HTML page on the elements tab. The HTML follows the parent-child relationship between the elements.
