Your example with the “8” doesn’t show different results but I think I understand where you want to go.
I’m not 100% confortable with wrapping children options but I have a way of doing this that I use a lot for grid-like layout.
1 - setup a parent div and set it to display flex (leave the default setting justify start and align stretch) and activate wrap children
2 - setup some div inside as flex items and activate the don’t shrink option
3 - define how many columns you want. For example 3, and set up the width of the flex item to 100/3% (you can type this in the width field as Webflow will do the handy math)
4 - setup some padding on 4 sides of the flex item
5 - put whatever you want in those items and add as many item as you want FlexBox magic is happening.
If you want to go further you can also play with this project which is a game/tutorial to make you understand all about FlexBox options :
I hope it will help you.
