HTML <iframe> Tag with the 'seamless' Attribute

<iframe src="iframe_example.cfm" width="150" height="150" seamless></iframe>

The above example demonstrates usage of the <iframe> element that uses the seamless Attribute.

The <iframe> element represents a nested browsing context. The seamless attribute can be used to specify that the nested browsing context is to be rendered in a manner that makes it appear to be part of the containing document (seamlessly included in the parent document). This results in the parent document's styles being applied to the nested content. It also results in any links being opened in the <iframe> element's parent browsing context.
