HTML stands for Hypertext Markup Language. It's like the basic building blocks for creating web pages. Think of it as the skeleton of a website. It uses special codes, which we call 'tags', to structure the content on the web page. These tags can create things like headings, paragraphs, links, and images. For example, if you want to write a headline on a website, you use a specific tag to make the text look like a headline. HTML tells the web browser (like Chrome, Firefox, or Safari) what each part of a web page is and how it should be displayed. It's the standard language that almost all websites use to organize and display their content in a way that people can see and interact with it in their web browsers. Without HTML, websites would be just plain text without any structure or visual organization.
