 | |
| ## 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 */
 | |
|   }
 | |
| ```
 | |
|
