What is Source Code?
Source code is the programming behind any specific website, web page, or URL. It's a group of programming languages written in a human-readable format that lies behind any live web page or URL.
What is HTML?
HTML stands for Hypertext Markup Language. It's the first layer of any web page that helps create structured sections, headings, paragraphs, blockquotes, and links. HTML builds the bones of any webpage, forming its skeleton.
HTML is not a programming language - you cannot define logic using it. A web structure consists of pages like home, about us, services, etc., and HTML is used to create this structure.
HTML History
HTML was created by Tim Berners-Lee in 1991. Since then, it has evolved through multiple versions:
- HTML 2.0 (1995)
- HTML 3.2 (1997)
- HTML 4.01 (1999)
- XHTML 1.0 (2000)
- HTML5 (2014)
