Not sure if everyone already knows this… but I just figured out that if you add
.MMM-GoogleSheets table {
background-color: transparent !important;
border-collapse: collapse;
}
.MMM-GoogleSheets td,
.MMM-GoogleSheets th {
background-color: transparent !important;
color: white !important;
border: none !important;
}
to your custom.css, the background becomes transparent!
(nice if you use, eg, https://github.com/parnic/MMM-Unsplash for a nicer background)
Thought I’d share this just for the fun of it.
Best,
