What is HTML?

  • HTML is a markup language. The word markup was used by editors who marked up manuscripts (usually with a blue pencil) when giving instructions for revisions. "Markup" now means something slightly different: a language with specific syntax that instructs a Web browser how to display a page. Once again, HTML separates "content" (words, images, audio, video, and so on) from "presentation" (instructions for displaying each type of content). HTML uses a pre-defined set of elements to define content types. Elements contain one or more "tags" that contain or express content. Tags are enclosed by angle brackets, and the closing tag begins with a forward slash.
    The basic HTML code structure is shown below:
    <html>
    <head>
        <title>Page title here</title>
    </head>
    <body>
        This is sample text...
        <!-- We use this syntax to write comments -->
        <!-- Page content and rest of the tags here.... -->
        <!-- This is the actual area that gets shown in the browser -->
    </body>
    </html>
    Most browsers allow the user to view the HTML of any webpage. In Firefox, for example, press Ctrl + U to view the page source. Beginners will find the code nearly unreadable for a complex page, but if you spend some time looking at the code for a simple page and comparing it to the page the code renders, you will soon develop a clear understanding of how the syntax works.
    The paragraph element consists of the start tag "<p>" and the closing tag "</p>". The following example shows a paragraph contained within the HTML paragraph element. Remember that your browser will not display more than one space character in a row.
