Module1--Introduction to HTML

HTML stands for Hyper Text Markup Language. Where Markup is information that is added to a document to convey information about the document structure or presentation.
 Consider a general scenario. There is a markup behind word processing software for aligning text and other graphical elements in your document, but the markup can't be visible. In the same way every HTML document (Web Page) which contain a markup which is not hidden and is used to tell web browser how to structure and some may say display web page.    
So HTML document is simply a document file with extension .html which contains markup instructions indicating how the browser should structure or present the web page.

The basic element of an HTML document is called Tags. A tag have the following structure.
    <tag_name> Where tag_name is the name of a tag, which will be inserted in between a less than and a grater than key.

There are two different type of tags.
  1. Start tag <tag_name>
  2. End tag  </tag_name> 
So an HTML element has the following two type of structure.
  1. <tag_name> Content for the tag</tag_name>
  2. <tag_name/>
Eg: 
  1. <h1> Welcome to HTML </h1>
  2. <br/>
