HTML in Action

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

How HTML Works
HTML uses tags to structure content. Tags are like containers that tell the browser what to do.
- Opening Tag:
<h1> - Closing Tag:
</h1> - Content: The text or information inside the tags.
Together, they form an element: <h1>Hello</h1>
