HTML Iframes
An iframe, or Inline Frame, is an HTML element represented by the <iframe> tag. It functions as a 'window' on your webpage through which visitors can view and interact with another webpage from a different source.
Iframes are used for various purposes like:
- Embedding Multimedia: Easily integrate videos, audio, or animations from platforms like YouTube, etc.
- Including Maps: Embed maps from services like Google Maps directly into your site.
- Loading Forms and Widgets: Incorporate forms or widgets from other sources without writing complex code.
Syntax:
<iframe src="URL" title="description"></iframe>- The
srcattribute specifies the URL of the document you want to embed. - Iframes can include videos, maps, or entire web pages from other sources.
HTML Iframes Examples

<h2>HTML iframe Tag</h2>
<iframe src=

<!DOCTYPE html>
<html>
<body>
<h2>HTML iframe Tag</h2>
<p>
Content goes here

<iframe src=

</iframe>
</body>
</html>

<h2>HTML iframe Tag</h2>
<p>Content goes here</p>
<iframe src=
"https://media.geeksforgeeks.org/wp-content/uploads/20231227155729/jsonPrac3.html"

width="400"
style="border: none">
</iframe>
</body>
</html>

Best Practices for Using Iframes
While iframes offer significant flexibility, they should be used wisely to ensure they enhance rather than detract from the user experience.
- Security: Always use the sandbox attribute to restrict the iframe's capabilities unless you fully trust the content. This can prevent malicious scripts from running.
- Performance: Iframes can slow down your page loading times. Only use them when necessary and ensure the embedded content is optimized for fast loading.
- Accessibility: Provide alternative content for users who might not be able to interact with iframes. This can be done by placing text or links inside the <iframe> tags, which will only display if iframes are not supported.
