How do I select the "last child" with a specific class name in CSS?

This can be done using an attribute selector.

[class~='list']:last-of-type  {
    background: #000;
}

The class~ selects a specific whole word. This allows your list item to have multiple classes if need be, in various order. It'll still find the exact class "list" and apply the style to the last one.

This is a cheeky answer, but if you are constrained to CSS only and able to reverse your items in the DOM, it might be worth considering. It relies on the fact that while there is no selector for the last element of a specific class, it is actually possible to style the first. The trick is to then use flexbox to display the elements in reverse order.

ul {
  display: flex;
  flex-direction: column-reverse;
}

/* Apply desired style to all matching elements. */
ul > li.list {
  background-color: #888;
}

/* Using a more specific selector, "unstyle" elements which are not the first. */
ul > li.list ~ li.list {
  background-color: inherit;
}
<ul>
  <li class="list">0</li>
  <li>1</li>
  <li class="list">2</li>
</ul>
<ul>
  <li>0</li>
  <li class="list">1</li>
  <li class="list">2</li>
  <li>3</li>
</ul>

You can use the adjacent sibling selector to achieve something similar, that might help.

.list-item.other-class + .list-item:not(.other-class)

Will effectively target the immediately following element after the last element with the class other-class.
