: Even is the jQuery selector that selects the first, third, fifth (and so on) element of a page that is of the same type or that have the same class.

Example of what you get using the jQuery: even selector

In this example, when the button is clicked, the first, third, and fifth block will be selected and get their content filled with a background color.
Line 1
Line 2
Line 3
Line 4
Line 5

Step 1
You need to specify elements that are the same type or that have the same class.

<div class="line">Line 1</div>
<div class="line">Line 2</div>
<div class="line">Line 3</div>
<div class="line">Line 4</div>
<div class="line">Line 5</div>
<button>Click me</button>

Step 2

Finally, the following jquery indicates that when the button is clicked, the first, third, and fifth lines will get a background color.

$('button').click(function(){
	$('.line:even').css('background-color', '#bbbbff');
});
