The below code works properly in this jsbin but it does not work in either this codepen, this plunker or this jsfiddle.
Why not? How can I get it to work in the three locations where it does not?

Since every other site other than jsbin is using the secure version of
HTTPi.e.HTTPS, the request to get the contents from the sourcehttp://polygit.org/polymer+:master/components/is blocked. So, use secure connection and it will work in every other site.You can check the console for more information.
