The jQuery :nth-last-child() selector is used to select all elements that are the nth last child of their parent. The counting of elements starts from the last element. 

Syntax:

:nth-last-child( n | even | odd | formula )

Parameters: The :nth-last-child() selector contain parameters which are listed below:

  • n: It holds the child index number of the selected elements. The counting starts from the end. The index number of the first child is 1.
  • even: It selects all even child elements.
  • odd: It selects all odd child elements.
  • formula: It is used to specify the formula to select the child element. The formula can be in form of (an + b).

Below examples illustrate the :nth-last-child() selector in jQuery: 

Example 1: This example changes the background color to green and text color to the white of the second last heading of their parents (div tags).
