:nth-last-child CSS Pseudo Class

Description

The :nth-last-child pseudo-class is used to add style to elements based on the numbering in the element tree. Unlike the pseudo-class :nth-child, the count is not from the first element, but from the last.

Syntax

element:nth-last-child (odd | even | <number> | <expression>) {...}

Values

oddAll odd item numbers.
evenAll even item numbers.
<number>The serial number of the child relative to its parent. Numbering starts with 1, this will be the first item in the list.
<expression>It is given in the form an ± b , where a and b are integers, and n is a counter that automatically takes the value 0, 1, 2 ...

If a is zero, then it is not written and the record is reduced to b. If b is zero, then it is also not specified and the expression is written in the form an. a and b can be negative numbers, in which case the plus sign changes to minus, for example: 5n-1.
By using negative values of a and b, some results can also turn out to be negative or equal to zero. However, elements are affected only by positive values due to the numbering of elements starting at 1.
