Iframe Attributes:

Src: The Url / page to be loaded into the iframe.

Id: The correct identifier for an Iframe.

Name: Same as id, except its used as a work around for a netscape bug that effects dynamic loading of content into Iframes.

Height: The height of an Iframe. You can also use percentages here instead of pixels.

Width: The width of an Iframe. You can also use percentages here instead of pixels.

FrameBorder: Valid values here are either 1 or 0. In this example I am using borders at 0.

MarginWidth: Specifies the width of the margin to set in an Iframe.

MarginHeight: Specifies the width of the margin to set in an Iframe.

Scroll: Valid values are yes or no. Please note that if you have more content than the height of the Iframe the scroll bars will appear anyway. To over come this set the Iframe height to a larger number than the content.

Align: Valid values are top, left, middle, center and default. Note I find the implementation of the align value to be buggy and prefer to stick the Iframe into a layer and position it that way.
