1. What is HTML?

HTML is a markup language used to structure content on the web. It defines elements like headings, paragraphs, links, images, and forms, allowing browsers to render web pages correctly.

Key Characteristics of HTML:

  • Not a programming language (no logic or calculations)
  • Uses tags (`content`) to define elements
  • Works with CSS & JavaScript for styling and interactivity

    • Example:
    ```html



    My First Webpage


    Hello, World!


    This is a paragraph.




    ```
