Padding
Number¶
If this value is a number, it is applied to all sides (left, top, right, bottom).
Object {top, left, bottom, right}¶
If this value is an object, the left property defines the left padding.
Similarly, the right, top and bottom properties can also be specified. Omitted properties default to 0.
Object {x, y}¶
This is a shorthand for defining left/right and top/bottom to the same values.
