How to set padding and margins in Canvas Page Builder
Global padding for widgets can be found under Canvas > Settings > Canvas Extensions > Page Builder widgets. This sets the padding for EVERY WIDGET top/bottom and left/right.
Padding can now also be set PER WIDGET using the widget ‘styling’ options. Hover over each widget and click styling. This will ‘add to’ any global widget padding you have set.
Global margins for widgets can be found under Settings > Page Builder > Display. This sets margins for EVERY WIDGET.
You can also turn disable the bottom row margin for each row under Row styling settings per row.
To color the whole background now you can do this on a row level or widget level. For rows, click the paint brush icon next to each row to open the row styling and set the background color option. This will fill the whole row. For widgets, hover over each widget and click styling. Set the background color for that individual widget (widget background color can also be set for EVERY widget in Canvas > Settings > Canvas Extensions > Page Builder widgets).
