HTML, which stands for HyperText Markup Language, is a programming language used to create and structure content on the World Wide Web. It is the standard markup language for creating web pages and is used to describe the structure and formatting of a document written in HTML.

HTML consists of a series of elements, or tags, that are used to define the content and structure of a web page. These elements include headings, paragraphs, lists, links, and more. HTML also allows for the use of multimedia, such as images and videos, and can be used to create interactive forms and other interactive elements.

To create an HTML document, you can use a simple text editor like Notepad or TextEdit. The document must be saved with the .html file extension in order for it to be recognized as an HTML document by a web browser.

To add content to an HTML document, you can use various tags, such as the

tag to define a paragraph, the

tag to define a heading, and the tag to create a hyperlink. HTML also includes tags for formatting text, such as bold and italic, and for creating lists, tables, and forms.

HTML also allows for the use of Cascading Style Sheets (CSS) to define the style and layout of a web page. By using CSS, you can control the font, color, and layout of your web page, making it easier to create a consistent look and feel across multiple pages.

In addition to being used for creating web pages, HTML is also used to create email messages and mobile applications. It is an essential skill for anyone looking to work in web design or development, and it is a fundamental building block of the World Wide Web.
