HTML (HyperText Markup Language) is the standard markup language used to create web pages. It defines the structure and content of a webpage, telling browsers how to display text, images, and other media. HTML uses a series of elements, represented by tags, to mark up different parts of content. HTML is not a programming language; it's a markup language that defines the structure of your content. ## How HTML Works HTML documents are plain text files with a `.html` extension.
