HTML (HyperText Markup Language) is the standard markup language used to create and design webpages. It structures the content on the web by using elements or tags that define different parts of a page, such as headings, paragraphs, links, images, and more. These tags help browsers understand how to display the content to users.

HTML is the backbone of any webpage and works in conjunction with other technologies like CSS (for styling) and JavaScript (for interactivity) to create fully functional and visually appealing websites. It is easy to learn, making it an essential skill for anyone looking to enter the world of web development.
