The problem is basically stated in the title, and it occurs only under these conditions:
- parent element is
display: flex; (or inline-flex),flex-direction: column;, andflex-wrap: wrap; - child element is
display: grid; - not in PC browsers (Chrome, Firefox and Edge were all OK), but iPhone browsers (Safari, Chrome, Google App and Firefox)
I avoided using this element structure so this doesn’t bother me anymore, but I’m still curious if this is a bug or correct behavior.
If it’s not a bug, how can I fix my code to make it look the same on PC and mobile?
Thanks for your attention!
Note: I checked on Google Chrome, Firefox, Microsoft Edge (Windows 10 PC) / Safari, Google Chrome, Google (app), Firefox (iOS 16.7.7 iPhone 8).
It works as I expected in all browsers on PC, but in all browsers on iPhone, does not.
Edit: Later I checked Chrome and Safari on iPad, and the result was same as iPhone.

Edit 2: It works fine when one of the children has content large enough to contain any line breaks such as long text or multiple inline-elements, but does not when the contents are block elements.
