The <iframe> tag in HTML stands for "inline frame." It allows you to embed another webpage, document, or media inside the current webpage. The <iframe> element is commonly used to display external content, such as maps, YouTube videos, advertisements, or other websites.
📌 Key Features of <iframe>

Supports both same-origin and cross-origin content embedding (with restrictions).
🔹 Basic Syntax of <iframe>
Here’s the basic structure of an <iframe> in HTML <iframe src="https://example.com" width="600" height="400"></iframe>
🔹 Explanation:

📌 Example: Embedding a Website Using <iframe>
Let's say you want to embed Google Maps in your webpage. Here's how you can do it:

<head>
<meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Embedding Google Maps</title> </head>
<body> <h2>Our Location</h2>
<iframe src="https://www.google.com/maps/embed?pb=!1m18!1m12!1m3!1d3151.835434509365!2d144.95373631567893!3d-37.81720974202148!2m3!1f0!2f0!3f0!3m2!1i1024!2i768!4f13.1!3m3!1m2!1s0x6ad642af0f11fd81%3A0x5045675218ce7e33!2sMelbourne%2C%20Australia!5e0!3m2!1sen!2sin!4v1629398412425!5m2!1sen!2sin" width="600" height="450" style="border:0;" allowfullscreen="" loading="lazy"> </iframe>
