<title>CSS Containment Test: Size containment on grid container with explicit non-intrinsically sized tracks (and gaps)</title>

<meta name=assert content="grid-gap, grid-template-columns, and grid-template-rows do affect the size of the grid, even with size containment">

<style>
body {
  overflow: hidden;
}
div {
  position: absolute;
}
#red {
  background: red;
  width: 100px;
  height: 100px;
}
#test {
  background: green;

  contain: size;
  display: grid;
  grid-gap: 20px;
  grid-template-columns: auto 80px; /* 0 + 20 + 80 = 100 */
  grid-template-rows: 40px 40px; /* 40 + 20 + 40 = 100 */
  font-size: 800px;
}
</style>

<p>Test passes if there is a filled green square and <strong>no red</strong>.</p>
<div id=red></div>
<div id=test>&nbsp;</div>

<!--
The &nbsp;, auto sized column, and 800px font size
are to make the test fail in browsers
that do not implement contain:size at all,
by making the box non square.
