How do I change the properties of a row?

1 Select the row

Hover your mouse over an area of the canvas that is free of content and click.

2 Modify row properties

On the right side of the editor you will now be shown some properties.  Will be applied to the whole row (e.g. background colour, background image, padding, etc.) ...

If you have more than one column, you can modify properties in each of them.
