Which language is primarily used for web development?

HTML is the primary language used for web development because it is the standard markup language that structures the content on the web. By defining elements such as headings, paragraphs, links, images, and other content, HTML creates the framework of a webpage. It is essential in establishing the hierarchy and organization of information, which enables browsers to render pages correctly for users.

While other languages, such as Visual Basic, COBOL, and FORTRAN, have their specific applications, they are not primarily designed for web development. Visual Basic is commonly associated with desktop applications and automation tasks, COBOL is primarily used in business and financial systems, and FORTRAN is used mainly in scientific and engineering applications. Thus, in the context of web development, HTML stands out as the foundational technology enabling the creation and display of web pages.
