Reply To: [Solved] Having a problem with border delcaration breaking flexbox layout

[Chris Coyier]

Pretty weird! I tinkered with it for a minute thinking it would be fairly obvious but it wasn’t to me at all.

I did discover that without the border there, the browser renders it at 0 width, hence the weird collapsing/breaking. Also using padding in that rule “fixes” it just like border does.
