title: CSS hover inner element on outer hover
body: <p>I would like to apply the hover state to the inner input element of the following link by hovering the image:</p>
  
  <pre><code>&lt;a href="#"&gt;&lt;img  src="img.png"&gt;
      &lt;div class="btn-u"&gt;Hackschnitzel&lt;/div&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>So hovering the image should result in the same state as hovering the button (right state - button is green)</p>
  
  <p><a href="https://i.stack.imgur.com/8qVhV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8qVhV.png" alt="enter image description here"></a></p>
  
  <p>Is there a way to achieve this with CSS only?</p>
  
  <p>EDIT: As the class for hover of <code>btn-u</code> already exists, I don't want to redefine those values and want to reference from <code>a:hover</code> to apply <code>btn-u:hover</code> as well</p>
