Padding defines the space between the inside border and content. A margin sets spacing outside a border, whereas padding adds space inside a border.
To optionally update all padding values at once, press the Set All button for Padding in the properties panel.
Click the value field for a border item. A spin control appears in that field.
Use the spin control to increase or decrease border width. If Set All was selected, the change is applied to all values.
The component is immediately repositioned using its new padding setting.
