HTML is a type of text code that tells browsers how to display a page on your screen. This code, sometimes called "markup", uses "tags“ (which, when embedded in a document, allows that document to be read and distributed across the Internet) that instruct a browser to make text a certain size or style, display an image, or link to another page or web site.
