Does this CSS identifier align with the specifications?

There appears to be an issue. The styles assigned to the second element should change when hovering over it, only if the third element has the class .active.

CSS:

li:nth-child(3).active ~ li:nth-child(2):hover

HTML:

 <ul>
    <li>
      <h1 id="logo">Logo</h1>
    </li>

    <li>
      <a href="#">Products</a>
    </li>

    <li class="active">
      <a href="#">Parts</a>
    </li>

    <li>
      <a href="#">Resources</a>
    </li>
  </ul>

Answer №1

If you are looking to target li:nth-child(2) only when li:nth-child(3) has the class .active, it can be tricky because CSS sibling combinators like + and ~ do not work backwards.

You may need to adjust your HTML structure to meet these conditions, or consider using DOM traversal as a simpler alternative.

Answer №2

To apply a hover effect to the active li, simply use this selector: li.active:hover

Check out this example fiddle

If you'd like to select the li before the active one, JavaScript will be necessary.

Alternatively, identify the li preceding the current active li during JSP (or your preferred technology) rendering and add the appropriate hover effect.
