This page shows how you can put the recent spins in an iframe.
Source code for this demo web site is on Bitbucket
The height of the iframe on this page is set by this page's stylesheet. It does not adjust according to the height of the content. If the content it too big, it displays a scroll bar. If too small, there's blank space. The JavaScript widget does not have this problem.
You can automatically adjust the iframe's height to fits its content with some extra work explained here. Our Schedule and Current playlist page demos use that technique.
