HTML Iframes

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

Iframe Syntax

The syntax for adding an iframe is:

<iframe src="URL"></iframe>

The src attribute specifies the URL (web address) of the iframe page.

Use the height and width attributes to specify the size.

The attribute values are specified in pixels by default, but they can also be in percent (like "80%").

<iframe src="demo_iframe.htm" width="200" height="200"></iframe>

The frameborder attribute specifies whether or not to display a border around the iframe.

Set the attribute value to "0" to remove the border:

<iframe src="demo_iframe.htm" frameborder="0"></iframe>

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:

<iframe src="demo_iframe.htm" name="iframe_a"></iframe>
<p><a href="http://www.w3schools.com" target="iframe_a">W3Schools.com</a></p>
