.red {
  position: absolute;
  z-index: -1;
  width: 100px;
  height: 100px;
  background: red;
  margin-left: 100px; /* moving right to skip the first 100x100 space that starts each line */

  vertical-align: sub;
  color: red;
}
</style>

<p>Test passes if there are 3 filled green squares and <strong>no red</strong>.</p>
<div class="red"></div>
<div class=test> <span>xxxx<br><div class="red"></div> xxxx<br><div class="red"></div> xxxx</span> </div>
<!-- 
There are 3 lines in the test div to make sure that the middle one only contains text from the span, not directly from the block,
guaranteeing that the ellipsis is taking its baseline from the block even when the block has no direct content on the line.

The "red" divs for line 2 and 3 are descendants of the span so that they are placed based on their static position at the begining of each line.
The alternative, which would be to place them (vertically) with explicit offsets would require knowing
the precise height of the preceeding line boxes, which isn't reliable across UAs.
