Slide 7.5: HTML iframes

HTML Iframes

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

Syntax for adding an iframe is shown on the right. The URL points to the location of the separate page.

  <iframe src="URL"></iframe>

Set Height and Width
The height and width attributes are used to specify the height and width of the iframe. The attribute values are specified in pixels by default, but they can also be in percent (like “80%”).

Use iframe as a Target for a Link
An iframe can be used as the target frame for a link. The target attribute of a link must refer to the name attribute of the iframe.
