Specifically, in the Instructions field for Assignments.
It gives me a tiny height viewport, but the "Width" tag appears to work.
If I manually set the height, to say, 1500px, it works fine, but I'd like it to do it automatically, in case the content changes later.
Code Example:
<object type="text/html" height="100%" width="100%" data="http://www.colorado.edu"> </object>
