The Noob's (in)complete guide to CSS for Hubitat

Hopefully, this is it, or at least on the right track. The previous example used variable number, I changed it to a variable string and was able to hide it using

#tile-11 > div.flex.flex-col.w-full.text-center.h-full > div.flex-grow-0.w-full {
   visibility: hidden;
}

I'll be gone for several hours hopefully someone has figured it out by then if this doesn't work.
