Outer spacing and inner spacing are the space around a widget. Margin is the space outside of the element's borders; padding is the space inside these borders. When you adjust the outer spacing and inner spacing of a widget, you change its placement and appearance. This can make your Site look more customised and professional.
1. Right-click on any widget, column, or row and then click Edit Design.
2. Click the Spacing tab.
To change the outer spacing (margin), click and edit the numbers in the outer box. You can also click on one of these numbers and use the slider to adjust the size.
To change the inner spacing (padding) click and edit the numbers in the inner box. You can also click on one of these numbers and use the slider to adjust the size.
Things to consider
If you see odd spaces that you can't remove, make sure you check all parts of the widget, including the column in which it is located.
