This is a shorthand property which allows an author to specify 'margin-top',
'margin-right', 'margin-bottom', and 'margin-left' properties using a single
property and value notation (the values are given in this order separated
by spaces.) If one or more of the values are not present, the value for a
missing side is taken from the opposite side that is present. If only one
value is listed, it applies to all sides.
CSS margins are transparent and the background value of the parent element
shines through. Negative values are allowed for each margin value of this
property, which opens the way for text overlays to be created.
