Is there a way to remove gap between this two layers ? I’m guessing somewhere in “Advanced Composite View Layout” but really i don’t know how to do this.
You can create a row and nest those two widget (rows). In the Advanced Composite View Layout section insert a “additionalStyles” : [ “background-color: green;” ] that will set the background of those two widgets. Use it right after the “type”: “row” row and right before the last.
