Dimension - Padding
The Padding properties add space around the content a component contains within the defined border of the component in all the four sides, i.e. Top, Bottom, Left and Right.
Remember, you need to provide the padding in the number of pixels here.
Adjusting the Padding of a Component
As you click on the component around which you want to add padding, the Style Manager of that component opens automatically in the Right Toolbar. You only have to go to the category, "Dimension" and adjust the top, bottom, right and left padding of the component as yout want.
Pixels, Percentage, Viewport, EM & REM
You can also assign the size in fixed pixels, % of screensize, viewport width, em and rem.
