HTML Iframes

Learn how to use HTML <iframe> tags to embed web pages within your document, customize dimensions, remove borders, and control links with target attributes.

An HTML iframe is used to display a web page within a web page.

Syntax

The HTML <iframe> tag specifies an inline frame.

An inline frame is used to embed another document within the current HTML document.


<iframe src="url" title="description"></iframe>

Set Width and Height of iframe

You can set the width and height of iframe by using width and height attributes. By default, the attributes values are specified in pixels but you can also set them in percent. i.e. 50%, 60% etc.


<iframe src="a-page.html" height="200" width="300" title="Iframe Example"></iframe>

Or you can add the style attribute and use the CSS height and width properties:


<iframe src="a-page.html" style="height:200px;width:300px;" title="Iframe Example"></iframe>

Remove the border of iframe

By default, an iframe contains a border around it. You can remove the border by using <style> attribute and CSS border property.

<!DOCTYPE html>
<html>
<body>
<h2>Remove the Iframe Border</h2>
<p>This iframe example doesn't have any border</p>
<iframe src="https://www.wikipedia.org" style="border:none;"></iframe>
</body>
</html>

Iframe - Target for a Link

An iframe can be used as the target frame for a link.

The target attribute of the link must refer to the name attribute of the iframe:

<!DOCTYPE html>
<html>
<body>
<h2>Iframe - Target for a Link</h2>
<iframe height="300px" width="100%" src="https://www.wikipedia.org" name="iframe_a"></iframe>
<p><a href="https://www.google.com" target="iframe_a">Google</a></p>
<p>The name of iframe and link target must have same value else link will not open as a frame. </p>
</body>
</html>
