  div {

    font-size: 3em;
    line-height: 1; /* Not strictly needed, but it gets quite tall otherwise, so this helps fit the screen. */

    hyphens: manual;
    margin: 1em auto;
  }
  .ref { color: orange; }
  span { color: transparent; }

<p>Test passes if the black text is identical to the orange text (except the color).

<!--
Using an invisible hyphen because it isn't certain what character the UA will actually use,
and we shouldn't fail the reftest because of a mismatch there.
See also hyphens-shaping-002.html to check that some character is inserted.
