Following the thread here: Customize container column width with CSS
Implemented the suggestions exactly, and found that upon publishing the app is unable to load and stuck on a black screen. I don’t get too many obvious things in the browser console other than: Error building column: Column not found.
The users in thread seem to have found success in implementing the custom CSS component on their page. One question I have is whether or not I should set the renderer to something other than HTML, but those haven’t seemed to fix the problem.
Any pointers as to why this would happen?
