It looks like it's not a CSS selector as its not on this list: https://www.w3schools.com/css/css_pseudo_classes.asp

It seems to be simply a jQuery selector: https://www.w3schools.com/jquery/sel_even.asp

The equivalent selector in CSS would be (however this starts counting from 1 unlike the jQuery version): 

li:nth-child(even) {
   background-color: red
}

Hi,

Here is the link: http://api.jquery.com/not/

As per the description, given the following list: 

<ul>
  <li>list item 1</li>
  <li>list item 2</li>
  <li>list item 3</li>
  <li>list item 4</li>
  <li>list item 5</li>
</ul>

The following method call will select 2 and 4 and set their background color to red. This may seem strange at first but :even and :odd use 0-based indexing.

$( "li" ).not( ":even" ).css( "background-color", "red" );

It's a CSS property?
