Introduction to HTML

HTML stands for Hypertext Markup Language, and it is the most widely used language to write Web Pages.

  • Hypertext refers to the way in which Web pages (HTML documents) are linked together. Thus, the link available on a webpage is called Hypertext.
  • As its name suggests, HTML is a Markup Language which means you use HTML to simply "mark-up" a text document with tags that tell a Web browser how to structure it to display.

Originally, HTML was developed with the intent of defining the structure of documents like headings, paragraphs, lists, and so forth to facilitate the sharing of scientific information between researchers.

Now, HTML is being widely used to format web pages with the help of different tags available in HTML language.

  • HTML is the language for publishing web pages on the WWW (World-Wide Web).
  • HTML is a Document Description Language (aka Document Markup Language). HTML is NOT a programming language like C/C++/C#/Java, which is used to implement programming algorithm.
  • You need a web browser to view the HTML pages. The web browsers do not display the HTML tags, but uses the tags to interpret the content of the web pages.
  • An HTML document is a text document, and it is human-readable.

HTML was originally developed by Tim Berners-Lee in 1990. He is also known as the father of the web. In 1996, the World Wide Web Consortium (W3C) became the authority to maintain the HTML specifications. HTML also became an international standard (ISO) in 2000. HTML5 is the latest version of HTML. HTML5 provides a faster and more robust approach to web development.

There have been many versions since the early days of the web as you can see.

What is HTML5?

HTML5 is the fifth version of the HTML scripting language. It supports a lot of new things that older versions of HTML does not. For Example: In HTML5 there is something new called the Semantic Elements. Semantic elements have meaningful names which tell about the type of content. For example header, footer, table, … etc. HTML5 introduces many semantic elements which make the code easier to write and understand for the developer as well as instructs the browser on how to treat them.
