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.

If your selector is a:last-child, this works −
<div> <a></a> <a>This will be selected</a> </div>
