# :nth-last-of-type() Selector

## nth-last-of-type ( index ) version added: 1.9

- index
  Type: Number/String
  The index of each child to match, starting with the last one (1), the string even or odd, or an equation ( eg. :nth-last-of-type(even), :nth-last-of-type(4n) )

Description: Selects all elements that are the nth-child of their parent, counting from the last element to the first.

Because jQuery's implementation of `:nth-` selectors is strictly derived from the CSS specification, the value of `n` is "1-indexed", meaning that the counting starts at 1. For other selector expressions such as `:eq()` or `:even` jQuery follows JavaScript's "0-indexed" counting. Given a single `<ul>` containing three `<li>`s, `$('li:nth-last-of-type(1)')` selects the third, last, `<li>`.

Further discussion of this usage can be found in the W3C CSS specification.

## Examples:

#### Example: Find the second to last li in each matched ul and note it.
