SUMMARY
In certain situations, you may want to resize an IFrame so that all of its document contents are visible, but no scroll bars are displayed on the page. This article describes how to do this.
Back to the topMORE INFORMATION
To determine the size of the IFrame's contents, you must access the height and width properties of the underlying IFrame document. Because you only have scripting access to pages that are hosted in the same domain, you can only access the properties to the pages that are hosted within the same domain (for example, Cross Frame Scripting). Therefore, the source document of the IFrame must be from the same domain as the page that contains the IFrame.
The following code demonstrates how to resize an IFrame in this way. Create a new .htm document, and paste the following HTML code. In the SRC attribute for the IFrame, you must supply an HTML page from the same domain that the IFrame loads.
NOTE: This technique may not work correctly if there are absolutely positioned elements that are residing within the IFrame.

oFrame.style.width = oBody.scrollWidth +
(oBody.offsetWidth - oBody.clientWidth);
}

its container's domain
