What is HTML File Format

HTML (HyperText Markup Language) is the standard markup language for documents created for display in browsers. The latest variant, known as HTML 5, gives a lot of flexibility for working with the language. HTML pages are either received from a server where these are hosted or can be loaded from a local system as well. 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.
