Margin shorthand property allows you to specify all necessary values at once separated by gaps. What happens if you don't define all 4 of them?

• When you set only one value, it applies to all four sides
• When you set two values, the first one defines the top and bottom margin, while the second defines the left and right margin
• When you set 3 values, the first one defines the top margin, the second defines the left and right, and the third defines the bottom
