Introduction to HTML

1. What is HTML?

• HTML stands for HyperText Markup Language.
• It is the standard language used to create web pages.
• HTML tells the browser what to display on the screen—like text, images, links, tables, forms, etc.
• It is not a programming language. It is a markup language because it uses tags to "mark up" content.

👉 Example:

<p>Hello, World!</p>

Here <p> is a paragraph tag. The browser will display Hello, World! as a paragraph.

2. History of HTML

• 1991 → Tim Berners-Lee (the inventor of the World Wide Web) introduced HTML.

• Early HTML had very few tags, mostly for text and links.

• Over the years, many versions came:

  • HTML 2.0 (1995) → First official standard.
  • HTML 3.2 (1997) → Added support for tables, applets, images.
  • HTML 4.01 (1999) → Widely used, introduced stylesheets (CSS).
  • XHTML (2000s) → Stricter version of HTML.
  • HTML5 (2014, latest major version) → Modern features like audio, video, canvas, offline storage.

👉 Today, HTML5 is the standard and is still being improved.

3. Capabilities of HTML

HTML by itself can:

1. Display Text → Headings, paragraphs, lists, quotes.

2. Add Links → Connect one page to another using <a>.

3. Insert Media → Images, audio, and video.

4. Create Tables → Organize data in rows and columns.

5. Create Forms → Collect user input (like login forms, search boxes).

6. Use Semantic Tags → <header>, <footer>, <article>, <section> for structured pages.

7. Work with CSS and JavaScript →

   • CSS adds design & style (colors, fonts, layout).
   • JavaScript adds interactivity (sliders, popups, games).

👉 HTML provides the structure, CSS adds the look, and JavaScript adds the behavior.
