Checkboxes exposing more content

The basic idea here is that if you check all the boxes, more stuff will be shown. Right now it’s set to need all 6 but it could be any number. Once again, it’s an ugly demo that we didn’t end up using but I can see this being useful in the future and it’s easier to find it on my own site than in Codepen’s dashboard.
