Assigning a class to every alternate item

Currently, I am in the process of compiling a list of products. To enhance the layout, I would like to assign a specific class to every other element. This class could be :before, :after, or simply .My-clas

<div class="product-single"></div>    
<div class="product-single"></div> <!-- A class needs to be added here -->    
<div class="product-single"></div>   
<div class="product-single"></div> <!-- Another class required here -->

Since the products will be added by the administrator, it is crucial for me to understand how to add a class to every other element. The exact number of elements added by the administrator may vary, so this alternating class addition is essential for the overall design.

Answer №1

If you want to style elements without using jQuery or JavaScript, you can achieve that by utilizing the nth-child selector in conjunction with the after pseudo-element:

.product-single {
  background: green;
  height: 100px;
  float: left;
  margin: 10px;
  width: 100px;
}

.product-single:nth-child(even):after {
  content: ':after';
  display: block;
}
<div class="product-single"></div>    
<div class="product-single"></div> <!-- insert additional class here -->    
<div class="product-single"></div>    
<div class="product-single"></div> <!-- insert additional class here -->

Answer №2

$('.item-list:nth-child(even)').toggleClass('highlighted');

Answer №3

If you want to alternate the styling of certain div elements, you can use the odd / even selector.

$('div:odd').addClass('alternateClass');
.alternateClass {
  background-color: lightblue;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="product-single">1</div>
<div class="product-single">2</div>
<!-- apply alternate class here -->
<div class="product-single">3</div>
<div class="product-single">4</div>
<!-- apply alternate class here -->
