Each HTML page is made up of HTML elements such as forms, text, images, animations, links, etc. These elements are represented by tags such as img, a, p and several others, where each tag has a start and end. It can also embed applications written in scripting languages such as JavaScript and Style Sheets (CSS) for overall layout representation.
