HTML (HyperText Markup Language) is the foundational language used to create and structure content on the web. It defines the layout and elements of web pages, such as headings, paragraphs, images, and links. HTML works seamlessly with CSS and JavaScript to build fully functional and visually appealing websites. It is essential for responsive and accessible web design. We can also work on this technology to develop clean, well-structured, and user-friendly web interfaces.
