This appears to be yet another bug in the Flexible Box Layout Module involving flex-direction: column
and flex-wrap: wrap
.
Browsers seem to be all over the place on this issue.
In this particular case, as stated in a bug report:
It seems to me that the width is calculated as if the inside elements were laid out horizontally (
flex-direction: row
) instead of vertically.
In other cases, the opposite occurs:
In both cases, there are currently no flex methods to resolve the problem.
For this particular question, one developer offers a CSS workaround, but I’m not sure it works in all browsers. I wouldn’t recommend it unless you’re truly desperate:
In some instances, you may be able to workaround this issue by using
vertical writing mode.That is, instead of using
flex-direction: column;
, use
flex-direction: row; writing-mode: vertical-lr;
. Remember to reset
towriting-mode: initial;
in the children of the flexbox.https://bugs.chromium.org/p/chromium/issues/detail?id=507397
