In particular, the flex-item-specific "min-height:auto" behavior is supposed to be disabled (e.g. we end up with min-height:0) when "overflow-y" is non-"visible". --> <style> .flexbox { display: flex; flex-direction: column; height: 30px; /* Shrink flex items below min-height */ margin-right: 2px; /* (Just for spacing things out, visually) */ float: left; } .flexbox > * { /* Flex items have purple border: */ border: 2px dotted purple; } .flexbox > * > * { /* Flex items' contents are gray & fixed-size: */ background: gray; width: 40px; height: 80px; } .yvisible { overflow-y: visible; } .yhidden { overflow-y: hidden; } .yscroll { overflow-y: scroll; } .yauto { overflow-y: auto; } </style> </head> <body> <!-- min-height:auto should prevent shrinking below intrinsic height when the flex item has "overflow-y: visible", but not for any other overflow-y values. --> <div class="flexbox"><div class="yvisible"><div></div></div></div> <div class="flexbox"><div class="yhidden"><div></div></div></div> <div class="flexbox"><div class="yscroll"><div></div></div></div> <div class="flexbox"><div class="yauto"><div></div></div></div> </body> </html>
