NOTE!!! nth-last-child counts from the end, so take that into consideration when looking at these
tests. For instance, the third child is the third child from the end, 'even' or 'odd' are even
or odd from the end, etc.

:nth-last-child(3) (selects third child)

:nth-last-child(0n+1) (selects first child)

:nth-last-child(1n+0) (selects all)

:nth-last-child(n+0) (selects all)

:nth-last-child(n) (selects all)

:nth-last-child(even) (also tests ':nth-last-child(2n+1)')

:nth-last-child(odd) (also tests ':nth-last-child(2n)')
