HTML, or HyperText Markup Language, is fundamental for creating web pages because it provides the basic structure and framework for web content. It allows developers to define headings, paragraphs, links, images, and other essential elements of a webpage. HTML uses a system of tags to format text and create a hierarchy of content, enabling browsers to render websites in a way that users can visually interpret.

While XML serves as a markup language for data storage and transport, it doesn't inherently present content as a web page. CSS, or Cascading Style Sheets, is used to style and layout HTML elements, but it cannot create the content itself. JavaScript is a programming language that adds interactivity to web pages, enhancing user experiences, but like CSS, it does not structure the content. HTML remains the core language for constructing the actual content and elements that make up web pages, establishing its critical role in web development.
