What is HTML?

HTML stands for HyperText Markup Language, the standard language for creating web pages and web applications. It is the backbone of any website, used to define the structure and layout of a web page. HTML uses a series of elements or tags to organize content into headings, paragraphs, images, links, and more.

Key Points:

  • HyperText: Refers to the way web pages are linked together using hyperlinks.
  • Markup Language: Refers to the syntax and structure used to annotate text and add meaning to content.

Why is HTML Important?

HTML is fundamental for web development because it:

  1. Provides the structure for web pages.
  2. Supports embedding multimedia like images, videos, and audio.
  3. Forms the foundation for styling (via CSS) and interactivity (via JavaScript).
  4. Is essential for Search Engine Optimization (SEO) as it helps search engines understand the content.

Basic Structure of an HTML Document

An HTML document follows a specific structure that includes key elements:

<!DOCTYPE html>
<html>
<head>
    <title>My First HTML Page</title>
</head>
<body>
    <h1>Welcome to HTML</h1>
    <p>This is a paragraph of text.</p>
</body>
</html>

Explanation:

  1. <!DOCTYPE html>: Declares the document type and version of HTML.
  2. <html>: The root element of the HTML document.
  3. <head>: Contains metadata (information about the page like title and links to CSS).
  4. <title>: Sets the title displayed in the browser tab.
  5. <body>: Contains all visible content like text, images and links.

Features of HTML

  1. Simple and Easy to Learn: Ideal for beginners.
  2. Platform-Independent: Works across different operating systems and browsers.
  3. Rich Media Support: Allows embedding of images, videos, and audio files.
  4. Extensibility: Can be integrated with CSS and JavaScript for advanced functionality.
  5. Search Engine Friendly: Helps web pages rank better in search engines when written correctly.

Key HTML Elements

Below are some basic HTML tags:

TagDescription
<h1> to <h6>Headings, <h1> being the largest and <h6> smallest.
<p>Defines a paragraph.
<a>Creates hyperlinks.
<img>Embeds an image.
