1. What are HTML and HTML5?
HTML stands for Hypertext Markup Language and is used to design web pages using markup language. HTML is a combination of hypertext, which defines the links between web pages, and markup language, which is used to define text documents within markup that define the structure of a web page. This language is used to annotate (in computer annotation) text so that a machine can understand it and manipulate the text accordingly.
Most markup (such as HTML) languages are human-readable. The language uses tags to define what operations must be performed on text. It is used to structure and render content on web pages.
