##IMPORTANT: This example uses gutter-position: inside
##Example:
nth-of-type(an+b)
nth-of-type(3n+1)
In that expression, the number b
represents the ordinal position of the first element that we want to match, and the number a
represents the ordinal number of every element we want to match after that. So our example expression, 3n+1
will match the first element, and every third element after that.
