## CSS3 Nth Child Selector
|
||
|
|
|
||
|
|
The `nth-child` selector is a css psuedo-class taking a pattern by which to match one or more elements relative to their position amongst siblings.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
```css
|
||
|
|
a:nth-child(pattern) {
|
||
|
|
/* Css goes here */
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Pattern
|
||
|
|
|
||
|
|
The patterns accepted by `nth-child` can come in the form of keywords or an equation of the form An+B.
|
||
|
|
|
||
|
|
#### Keywords
|
||
|
|
|
||
|
|
##### Odd
|
||
|
|
|
||
|
|
Odd returns all odd elements of a given type.
|
||
|
|
|
||
|
|
```css
|
||
|
|
a:nth-childe(odd) {
|
||
|
|
/* CSS goes here */
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
##### Even
|
||
|
|
|
||
|
|
Even returns all even elements of a given type.
|
||
|
|
|
||
|
|
```css
|
||
|
|
a:nth-childe(even) {
|
||
|
|
/* CSS goes here */
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
#### An+B
|
||
|
|
|
||
|
|
Returns all elements matching the equation An+B for every positive integer value of n (in addition to 0).
|
||
|
|
|
||
|
|
For example, the following will match every 3rd anchor element:
|
||
|
|
```css
|
||
|
|
a:nth-childe(3n) {
|
||
|
|
/* CSS goes here */
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
