Portfolio Problem with embedded Codepen windows

This is my portfolio. As you can see the Codepen windows aren’t working properly, but they do work when the the site is run locally (after adding http:// in front of the code), and in Codepen. How can I get these windows to display properly?

They seem to be working fine for me. What problems are you seeing?

Hey @hughwin,
It’s really awesome bro

I don’t know what happened, but they randomly started working just after I asked the question - I swear! Feel a little silly for posting the question haha
