The standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as CCS and JS.
Every website you open in your browser, from social networks to music services, uses HTML. A look under the hood of any website would reveal HTML code providing structure for all the page’s components.
Second, HTML lets us indicate the roles of different elements to search engines and other services that index the content and summarize it for other users. For instance, marking the caption of an image with the “figcaption” element and enclosing the image and its caption in the “figure” element helps a search engine understand that these two pieces of content are related, and that the caption describes the associated image.
