What is html ?

What is html

Hypertext Markup Language (HTML) is the standard markup language for creating web pages and web applications. With Cascading Style Sheets (CSS) and JavaScript, it forms a triad of cornerstone technologies for the World Wide Web

Hyper Text: HyperText simply means "Text within Text". A text has a link within it, is a hyper text. Every time when you click on a word which brings you to a new webpage, you have clicked on a hyper text.

Markup language: A markup language is a programming language that is used make the text more interactive and dynamic. It can turn a text into images, tables, links etc.

Features of HTML:

  • It is a very easy and simple language. It can be easily understood and modified.
  • It is very easy to make an effective presentation with HTML because it has a lot of formatting tags.
  • It is a markup language so it provides a flexible way to design web pages along with the text.
  • It facilitates programmers to add a link on the web pages (by HTML anchor tag), so it enhances the interest of browsing of the user.
  • It is platform-independent because it can be displayed on any platform like Windows, Linux, and Macintosh etc.
  • It facilitates the programmer to add Graphics, Videos, and Sound to the web pages which makes it more attractive and interactive.

History of HTML:

In the late 1980's, A physicist, Tim Berners-Lee who was a contractor at CERN, proposed a system for CERN researchers. In 1989, he wrote a memo proposing an Internet-based hypertext system.
Tim Berners-Lee is known as the father of HTML. The first available description of HTML was a document called "HTML Tags" proposed by Tim in late 1991.

The following is an example of the classic "Hello, World!" program, a common test employed for comparing programming languages, scripting languages, and markup languages. 

This example is made using 9 source lines of code:

<!DOCTYPE html>
<html>  
    <head>
           <title>This is a title</title>
    </head>
 <body>
           <p>Hello world!</p>
 </body>
</html>
