The :nth-child() selector in CSS is used to match the elements based on their position in a group of siblings. It matches every element that is the nth-child.
Syntax:
:nth-child(number) {
// CSS Property
}Where number is the argument that represents the pattern for matching elements. It can be odd, even or in a functional notation.
- odd: It represents the elements whose position is odd in a series: 1, 3, 5, etc.
Syntax:
element:nth-child(even)
- even: It represents the elements whose position is even in a series: 2, 4, 6, etc.
