This is the cross-axis baseline. The spec says this about this case: If the flex container has at least one flex item, and its first flex item has a baseline parallel to the flex container's cross axis, the flex container's cross-axis baseline is that baseline. --><html><head> <title>CSS Test: Testing the baseline of a vertical flex container with one flex item</title> <link href="mailto:dholbert@mozilla.com" rel="author" title="Daniel Holbert"> <link href="http://www.w3.org/TR/css-flexbox-1/#flex-baselines" rel="help"> <link href="reference/flexbox-baseline-single-item-001-ref.htm" rel="match"> <meta charset="utf-8"> <style> .flexContainer { display: inline-flex; flex-direction: column; height: 16px; width: 16px; background: purple; border: 0px dotted black; /* (Elements that want a border will set their border-width.) */ } </style> </head> <body> A <div class="flexContainer">a</div> <div style="padding-bottom: 20px" class="flexContainer">a</div> <div style="padding: 10px" class="flexContainer">a</div> <div style="border-width: 3px" class="flexContainer">a</div> <div style="border-bottom-width: 4px" class="flexContainer">a</div> </body></html>
