Introduction to HTML
HTML stands for HyperText Markup Language. It’s the standard language used to create web pages. HTML structures the content on the web, allowing browsers to display text, images, and other elements in a structured way.
Key Terminology
- HyperText: Text that contains links to other texts.
- Markup Language: A system for annotating a document in a way that is syntactically distinguishable from the text.
- Element: A component of HTML, defined by a start tag, content, and an end tag.
HTML’s Humble Beginnings
HTML was created by Tim Berners-Lee in 1991. It was designed to allow scientists to share documents easily over the internet. The first version, HTML 1.0, was very basic, focusing on simple text formatting and links.
Example: A Simple HTML Document
<!DOCTYPE html>
<html>
<head>
<title>My First HTML Page</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is my first HTML document.</p>
</body>
</html>This simple HTML document includes a title and a body with a heading and a paragraph. It’s the foundation of any web page!
Evolution Through Versions
HTML has gone through several versions, each adding new features and improving web capabilities. Let’s explore some key milestones:
- HTML 2.0 (1995): Introduced forms and tables, allowing for more interactive and structured content.
- HTML 3.2 (1997): Added support for complex tables and scripting languages like JavaScript.
- HTML 4.01 (1999): Focused on separating content from presentation, introducing CSS for styling.
- XHTML 1.0 (2000): A stricter version of HTML, aimed at improving web standards compliance.
- HTML5 (2014): Revolutionized web development with new elements like
<video>,<audio>, and<canvas>, as well as APIs for offline storage and more.
Example: HTML5 Features
<!DOCTYPE html>
<html>
<head>
<title>HTML5 Features</title>
</head>
<body>
<h1>Welcome to HTML5</h1>
<video width="320" height="240" controls>
<source src="movie.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;"></canvas>
</body>
</html>This example demonstrates HTML5’s ability to embed video and use the canvas element for drawing graphics. These features enhance multimedia capabilities on the web.
