+ <title>CSS Test: Testing min-height:auto</title> |
+ <link rel="author" title="Daniel Holbert" href="mailto:dholbert@mozilla.com"> |

+<!-- |
+ This testcase tests the used value of "min-height:auto" (the property's |
+ initial value) on flex items in a vertical flex container. |
+ |
+ It's supposed to resolve to the smallest of: |
+ a) The used 'flex-basis' (taken from 'height'), if 'flex-basis' is at its |
+ initial value. |
+ b) The computed 'max-height' property |
+ c) If there's no intrinsic aspect ratio: the item's min-content height. |
+ d) If there is an intrinsic aspect ratio: the item's height derived from |
+ the ratio & constraints in the other dimension. |
+ |
+ We measure what the used value is by putting flex items in a small flex |
+ container, which will shrink its items down to their min-height. |
+ |
+ This test checks for situations where we should resolve the min-height as |
+ (d) above, with "constraints in the other dimension" being |
+ max-width-clamped "width". |
