HTML stands for HyperText Markup Language. It is the foundation of all webpages and serves as the structural backbone that makes websites come alive. HTML is a language used to create webpages by adding tags to text files, which can be viewed in a web browser. These tags tell the browser how to display the website’s content on the screen. Without HTML, there would be no way for computers to communicate with each other and the World Wide Web would cease to exist.
