What I’m trying to do is create a horizontal stack for my ESPHome gate controllers. The first item in the stack is the cover control, but I also have an input boolean that I use to override the cover and hold the gate open if necessary.
But it looks dumb if the two cards share the row equally. I’d prefer to have the input boolean justified to the right, and have the cover control take up the equivalent of 3 spaces in the row.
Yes the custom:layout-card will let you choose the relative column widths either by pixels or percentage. It’s done on a per card basis. So if you had two cards side by side you could make one 75% and the other 25% wide.
