CSS :nth-last-child() Selector

Last Updated : 05 Jul, 2023

The nth-last-child() selector in CSS is used to match elements based on their position among the group of siblings, counting from the end.

Syntax:

:nth-last-child(number) {
    //CSS Property
}

Where number is the argument that represents the pattern for matching elements counting from the end. It can be odd, even or in a functional notation.

odd: It represents elements whose position is odd in a series: 1, 3, 5, etc., counting from the end.
even: It represents the elements whose position is even in a series: 2, 4, 6, etc., counting from the end.
functional notation (<An+B>): It represents elements whose position of siblings matches the pattern An+B, for every positive integer or zero value of n. The index of the first element, counting from the end, is 1.

Example 1: In this example every odd element is selected according to formula 2n+1, counting from the end.
