Such great news, thank you 
I am a small bit busy those days due to having to make a couple of websites, but I think I’ll be able to upload everything (after cleaning up a small bit the code) in the next days!
Of course the code is open source, it’s actually my first “contribution” to another project so it feels pretty awesome
Is there any preference about the css? I will add --vars on values that can be changed (console-width, cloze’s colours and the like). As of now, I used flexbox’s ordering to push the languages together at the top of the code, but they could also be seen as in the first screenshot, although I think it makes for harder design when it comes to prompts and explanations on longer codes…
Let me know what can help you the most 
I’ve also used BEM nomenclature for the code-card component to make the CSS easier to understand and followed a SMACSS methodology, so it should be rather easy to read.
Have a nice day!
