<title>CSS Values and Units Test: support for the ch unit</title>
<link rel="author" title="Cameron McCormack" href="mailto:cam@mcc.id.au">
<link rel="help" href="https://drafts.csswg.org/css-values-3/#font-relative-lengths">
<link rel="match" href="reference/ch-unit-013-ref.html">
<meta name="assert" content="The ch unit is equal to 0em if the zero glyph's advance is 0.">
<style>
@font-face {
  font-family: ChTestZeroWidthZero;
  src: url(resources/ChTestZeroWidthZero.woff);
}
div {
  height: 10px;
  background-color: blue;
  margin-top: 10px;
}
.test {
  width: calc(100px + 5ch);
}
.ref {
  width: 100px;
}
</style>
<p>The test passes if there are two blue rectangles of equal length.</p>
<!-- The '0' glyph in ChTestZeroWidthZero has a horizontal advance of
     zero, so ch units should compute to 0em, resulting in the div being
     100px wide. -->
<div class="test" style="font: 20px ChTestZeroWidthZero;"></div>
