Hyper Text Markup Language (HTML) is the standard markup language used to create web pages, allowing humans to structure and present content. HTML uses tags and attributes to determine what elements will appear on a web page, including text, images, audio, video, and more. With HTML, developers are able to create interactive forms and sophisticated hyperlinks with ease. By swiftly developing websites that are both accessible and aesthetically pleasing, HTML serves as an important tool in modern business.
