How-to for iFrames in Control Pages

I've searched and found some high level advice for creating Control Pages with custom HTML or iFrames. Can someone create a How-to-Wiki for doing this?

My end state goal is to create a control page that embeds my nest.com control page to create a more seamless experience for HA.

Did you see/try what is on this forum page:

Also Google on "iframe tutorial" and I imagine there will be some good examples. One caveat to note, however, is that Indigo Touch is not a Web browser. That is, you cannot point Indigo Touch to an arbitrary HTML page (with iframes). Indigo Touch only renders Indigo control pages which don't support iframes directly. But the iframe technique should work fine from Safari if that is what you are planning.
