HTML, or Hypertext Markup Language, is the standard markup language for creating web pages and web applications. HTML is used to structure and format content for display on a web page, and can be used to include images, video, and other multimedia. Additionally, HTML can be used to create interactive forms and to add event handlers, which allow the web page to respond to user input. With its wide range of capabilities, HTML is an essential tool for anyone looking to create a website or web application. Lastly, HTML5 adds plenty of new features to the language, making it more powerful and flexible than ever before. Whether you’re looking to create a simple web page or a complex web application, HTML is the foundation that you’ll need to use. However, it is important to note that HTML is not a programming language, it is simply a markup language used to structure content for display in a web browser. For more complex functionality, developers typically use a programming language such as JavaScript.
