<title>CSS Grid Layout Reference: block-axis 'auto' margins with explicit row placement</title>
<link rel="author" title="Sammy Gill" href="mailto:sammy.gill@apple.com">
<!-- Same layout achieved with align-items:center instead of auto margins. -->
<style>
#grid {
display: grid;
background: grey;
grid-template-columns: 100px;
grid-template-rows: 100px 100px;
align-items: center; /* center within the row in the block axis */
}
#grid div {
width: 100px;
}
#item1 {
grid-row: 1 / 2;
height: 20px;
background: green;
}
#item2 {
grid-row: 2 / 3;
height: 40px;
background: blue;
}
</style>
<p>The test passes if the green box and the blue box are each centered vertically within their grid row.</p>
<div id="grid">
<div id="item1"></div>
<div id="item2"></div>
