The:last-child selector not working as expected in HTML5

The last-child selector is used to select the last child element of a parent. It cannot be used to select the last child element with a specific class under a given parent element.

Style the last child li element with background-color −

li:last-child{
   background-color: blue;
}

It creates issues if the element is not the very last element.

Let us see an example of <a> −

If your selector is a:last-child, this works −

<div>
   <a></a>
   <a>This will be selected</a>
</div>
