.multicol {
  margin: 1em;
  border: solid silver;
  width: 300px;
  column-width: 100px;
  column-gap: 0;
  column-fill: auto;
  height: 100px;

.container {
  border: 15px aqua;
  border-style: none solid;
  height: 250px;

.clear {
  border-bottom: solid orange;

<p>The orange line should be halfway down the third column
(immediately after the end of the aqua lines).
