HyperText Markup Language (HTML) is a text-based markup language that's used to structure the content and layout of web pages. HTML is made up of markup symbols or codes that are inserted into a file to be displayed on the web. These codes, or elements, are written between angle brackets, such as < and >. Here are some things to know about HTML: How it works HTML tells web browsers how to display the words and images on a web page. Browsers receive HTML documents from a web server or local storage and then render them into web pages. How it's used HTML is used to structure content in a variety of ways, including paragraphs, lists, images, and data tables. How it's related to other technologies HTML is often used in conjunction with Cascading Style Sheets (CSS) and scripting languages like JavaScript.
