Downsize the card so I can get 3 or 4 in a row

[ZuhauseSYD]

The images of the carsd are really big, id like to scale them down somewhat, like you can with images for simple cards.
A way to resize on percent or something just so i can fot a row of 3 thermostats rather than row of 2 like it seems right now.

I tried to create a horizontal stack but it didn't seem tor ender, like it was fixed or something

The cards scale by their available width. If you add more columns, that would also give you more rows. Another workaround would be to resort to https://github.com/thomasloven/lovelace-card-mod to apply some custom CSS restricting the size of the card.

Create a horizontal stack and add 2 in there. It will make it smaller.
