• It provides a means to describe the structure of text-based information in a document  HTML is written in the form of labels (known as tags), surrounded by angle brackets.
  
• HTML can also describe, to some degree, the appearance and semantics of a document, and can include embedded scripting language code which can affect the behavior of web browsers and other HTML processors

• A web browser is a software application that enables a user to display and interact with text, images, videos, music and other information typically located on a Web page.
  
• Text and images on a Web page can contain hyperlinks to other Web pages at the same or different website.
  
• Web browsers allow a user to quickly and easily access information provided on many Web pages at many websites by traversing these links.
