There isn’t a CSS parent selector per say. However, you can use the :has() pseudo-class to find a parent element. Let’s see how!

HTML
Code
<style>
  .parent {
    background-color: #f5f5f5;
  }

  .parent:has(.child:hover) {
    background-color: #eee;
  }

  .parent:has(.child:focus) {
    background-color: #333;
  }
</style>

<div class="parent">
  <button class="child">Click this</button>
</div>
