One thing I'm wondering: do a post below a video and one on the channel 's community page have the same structure?

If that's the case, then you'd could tackle #409 too!

I think tackling 409 in this PR might overcomplicate this PR but I can look into it after this PR is merged

This is working great! The layout is a bit weird when replies are folded and the main message might benefit from a slightly different style, but that's minor and can definitely be addressed later ^^

Did some style improvements + added the ability to view community post comments without javascript 😄

Thanks for the PR!
