.test {
  width: 7ch;
  font: 20px monospace;
  background: blue;

  white-space: pre-wrap;
  text-align: justify;
}
.test > span {
  background: green;;
}
</style>
<p>Test passes if we have XX at each edge of the blue box and XXX in the second line (left-edge trailing space if not removed)</p>
<div class="test"><span>XX XX </span><span>XXX</span></div>
