Same for me, the yandex domain they're loading hljs from seems to be blocked. The hljs call is in the same script block as the line to initiate the fancy stuff, so it fails and that line's never reached. Paste this into the console to run that manually: $('.active form').card({ container: $('.card-wrapper')})
