The value of 0 works without specifying units in all situations where numbers with length units or percentages are allowed. There is no difference between 0px, 0em, 0%, or any other zero-value. The units aren't important because the value is still zero. CSS allows you to omit the length units for zero values and still remain valid CSS.
