<div>The purpose of a web browser is to read HTML documents and compose them into visible
or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret
the content of the page. HTML describes the structure of a website semantically along with
cues for presentation, making it a markup language rather than a programming language. </div>
