HTML (HyperText Markup Language) is the standard markup language used for structuring web pages and formatting content. HTML describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language. HTML works in conjunction primarily with CSS and JavaScript, adding style and behavior to the pages. The most recent revision to the HTML specification is HTML5.2.
