I ran into a problem when using flexbox.
I'm using a container with flex-direction: column; flex-wrap: wrap
, so my inner items can actually be placed in multiple columns.
The problem is that the browser still calculates the container's width as a sum of inner items' widths!
My container block should have a smaller width (based on content size), but it is actually huge.
Anyway, it's also very unnatural to calculate container's width this way when using columns, not rows.
Take a look at the green block in my code. It has a huge with, but it isn't supposed to have so. Also, it gets smaller as you remove an item from the container.
What I expect is to have the container with small width, so it wouldn't take more than a half of the available space.
Checked this on the latest Safari and Chrome on the latest OS X.
.container {
display: flex;
flex-wrap: wrap;
flex-direction: column;
background: #aa0000;
height: 100px;
}
.group {
display: flex;
flex-wrap: wrap;
flex-direction: column;
align-content: flex-start;
}
.g1 {
background: #00aa00;
}
.g2 {
background: #0000aa;
}
<div class="container">
<div class="group g1">
<div class="item">Item</div>
<div class="item">Item</div>
<div class="item">Item</div>
<div class="item">Item</div>
<div class="item">Item</div>
<div class="item">Item</div>
<div class="item">Item</div>
</div>
<div class="group g2">
<div class="item">Item</div>
</div>
</div>
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;
, useflex-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
