1. HTML is an acronym for Hyper Text Markup Language. It is a static language that determines the structure and semantic meaning of a web page. You use HTML to create content and metadata that browsers use to render and display information. HTML content can include text, images, audio, video, forms, lists, tables, and many other items. An HTML page can also contain hyperlinks, which connect pages to each other and to web sites and resources elsewhere on the Internet.
