<meta name="assert" content="An item spanning >1 track, at least one of which is flexible, must have a zero automatic minimum size (and thus, not grow to accommodate its children).">

<style>
.grid { display: grid; grid-template-columns: repeat(12, 1fr); height: 100px; width: 100px; }
.test { grid-column: 1 / span 8; grid-row: 1; background: red; }
.over { grid-column: 1 / span 8; grid-row: 1; background: green; }
.under { grid-column: 9 / span 4; grid-row: 1; background: green; }
.big-child { width: 500px; height: 100px; }
</style>

<p>Test passes if there is a filled green square and <strong>no red</strong>.</p>
