🌐 Introduction to HTML (HyperText Markup Language)
HTML, or HyperText Markup Language, is the standard language used to create and structure content on the World Wide Web. It forms the backbone of every website and is used to define the layout, text, images, links, and other multimedia elements on a webpage.
📜 What is HTML?
HTML is not a programming language; it is a markup language. It uses tags and attributes to annotate text, images, and other content for display in web browsers. These tags tell the browser how to display the content and provide structure to a webpage.
For example:
<h1>Hello, World!</h1>
<p>This is a paragraph.</p>
🧱 Structure of an HTML Document
A basic HTML document follows a specific structure:
<!DOCTYPE html>
<html>
<head>
<title>My First HTML Page</title>
</head>
<body>
<h1>Welcome to HTML</h1>
<p>This is a simple HTML page.</p>
</body>
</html>
Key Elements:
<!DOCTYPE html>: Declares the document type and version of HTML.<html>: Root element that wraps all the content.<head>: Contains meta-information like title, CSS, scripts, etc.<title>: Displays the title in the browser tab.<body>: Contains all visible content on the webpage.
