Need to ask for help/feedback/testing again.
Did some iframe trickery to get a page embed into another one with its full height, as then only 1 scrollbar is needed (from the main page).

If you have a few seconds, open up https://kx.studio/Board and tell me:
1. Do you see [kan]board style contents within the page content?
2. Is the content height correct? (that is, you can see the full thing)
3. Do you see only 1 scrollbar, or more?
4. Does anything look out of place?

Thanks!

First look: fine.

Second look: missing scrollbar or resize. Firefox, Ubuntu Focal.

BTW, please make this tutorial series!
