To edit the properties of a row/column, click on the structure you'd like to change. You will be given the chance to:
1. Delete the area
2. Duplicate the area
The right side of the editor will now show you some properties that apply to the entire row (e.g. background color) and some that apply to each column in the row. A row could contain multiple columns.
- Background color for that column
- Padding settings (for all sides or for each side)
- Border settings (for all sides or for each side)
