Official HTML5 Logo
HTML stands for Hyper Text Markup Language and is a computer language that is mainly used for the creation of web content. HTML is always composed inside an IDE, or Integrated Development Environment. Every HTML document is always appended with ".html". To see how the HTML code translates into content, simply open the document in a web browser and it will display the code in a human-readable format.

According to WHATWG (Web Hypertext Application Technology Working Group), an organization that has been 'maintaining and evolving HTML since 2004', stated on their website:
"...we moved to a new development model, where the technology is not versioned and instead we just have a living document that defines the technology as it evolves."
