I want to change the background color when the `li` anchors are clicked:

```html
<div class="text-center row">
  <ul  class="col-md-12 secondNav">
    <li class="navbar-brand nav-item" style="margin-right: 9%">
      <a href="#" ><strong>INICIO</strong> </a>
    </li>
    <li  class="navbar-brand nav-item" >
      <a href="#"><strong>COMPARAR</strong></a>
    </li>
  </ul>
</div>

```
