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

+<!--
+ This testcase tests the used value of "min-width:auto" (the property's
+ initial value) on flex items in a horizontal flex container.
+
+ It's supposed to resolve to the smallest of:
+ a) The used 'flex-basis' (taken from 'width'), if 'flex-basis' is at its
+ initial value.
+ b) The computed 'max-width' property
+ c) If there's no intrinsic aspect ratio: the item's min-content width.
+ d) If there is an intrinsic aspect ratio: the item's width 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-width.
+
+ This test checks for situations where we should resolve the min-width as
+ (a), (b), or (c) above. Another test will check (d).

+ /* Flex items have purple border: */
