I have three divs with its correponding span children in my html page
<ul>
   <li><div><span class="spinner">A</span></div></li>
   <li><div><span>B</span></div></li>
   <li><div><span>C</span></div></li>
</ul>
and I would like for only the one who has the children span class="spinner" to actually spin when I hover over the div but I cannot accomplish such task witht the following lines:
ul li div:hover span.spinner {
    animation: spin 1s linear infinite;
}
