Description  

The :nth-last-child(an+b) CSS pseudo-class matches an element that has an+b-1 siblings after it in the document tree, for a given positive or zero value for n, and has a parent element.

In effect, it functions the same as :nth-child except it selects items counting backwards from the end of element series, not the start.

See :nth-child for a more thorough description of the syntax of its argument.
