An HTML iframe (short for inline frame) is an HTML element used to embed another HTML document within the current document. It allows you to display content from another web page or website within your own web page. This is often used to embed videos, maps, social media feeds, or other external content.
Here's an example of how to use an iframe in HTML:
html
<!DOCTYPE html>
<html>
<head>
<title>Example Page</title>
</head>
<body>
<h1>Welcome to my website</h1>
<iframe src="https://www.example.com"></iframe>
<p>Some other content on the page.</p>
</body>
</html>
In this example, an iframe is used to embed the content of `https://www.example.com` within the current web page. The `src` attribute specifies the URL of the external content you want to display. You can also specify additional attributes for the iframe, such as `width`, `height`, `frameborder`, `allowfullscreen`, and more, to control its appearance and behavior.
It's important to note that the content within the iframe is treated as a separate document, so it has its own HTML, CSS, and JavaScript. This means that the content displayed within the iframe is not affected by the styles or scripts of the parent page, unless explicitly allowed through techniques like Cross-Origin Resource Sharing (CORS).
Keep in mind that the use of iframes should be done with caution, as they can have security and performance implications. It's recommended to only embed content from trusted sources and ensure that you have permission to display the content within your own website.
