Removes all margins.

When using 1 value, the margin is set for all 4 sides.

When using 2 values:

• the first value is for top/bottom
• the second value is for right/left

To remember the order think about the values you haven't defined.

If you enter 2 values (top/right), you omit setting bottom and left. Because bottom is the vertical counterpart of top, it will use top’s value. And because left is the horizontal counterpart of right, it will use right’s value.

When using 3 values:

• the first value is for top
• the second value is for right/left
• the third value is for bottom

To remember the order think about the values you haven't defined.

If you enter 3 values (top/right/bottom), you omit setting left. As right’s counterpart, it will use its value.

When using 4 values:

• the first value is for top
• the second value is for right
• the third value is for bottom
• the fourth value is for left

To remember the order, start at the top and go clockwise.
