Basic Structure of an HTML Document
Every HTML document begins with a defined structure that the browser can interpret. Here’s the core layout:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My First HTML Page</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a sample paragraph inside the body.</p>
</body>
</html>Key Components:
<!DOCTYPE html>: Declares the HTML5 document type.<html>: The root of the HTML document.<head>: Contains meta information, styles, scripts, and the title.<body>: Contains the visible content of the page.
Explanation of Each Core Tag
<!DOCTYPE html>
- Tells the browser to use HTML5.
<html>
- Wraps the entire document.
- Commonly includes
lang="en"to indicate language.
<head>
- Includes:
<meta charset>: Character encoding.<meta name="viewport">: Responsive layout for mobile devices.<title>: Page title shown in browser tab.
<body>
- Where all visible page elements go.
- Tags such as
<h1>,<p>,<img>,<div>, etc. are placed here.
