title: Target Sibling on Hover SCSS without JS?
body: <p>I have two divs which are at the same position but <strong>a</strong> has the higher z-index than <strong>b</strong>.</p>
  <p>When I hover <strong>a</strong> I want that <strong>b</strong> to change its width for example. Is this possible with CSS/SCSS?</p>
  <p>Sorry if this is a duplicate.</p>
  <pre><code>&lt;div class=&quot;a&quot;&gt;&lt;/div&gt;
  &lt;div class=&quot;b&quot;&gt;&lt;/div&gt;
  </code></pre>
