Firefox Inspector has useful visualizations for flexbox containers: https://developer.mozilla.org/en-US/docs/Tools/Page_Inspecto... And another useful feature that shows indicators why some CSS properties are not working.

Thanks, I use Firefox and didn't know about this. It's interesting, but seems like it'd be most useful if you were actually using flex basis and not that helpful for just basic justification and alignment.

Indeed! I should’ve dropped some of these screenshots or links to FF devtools in the post.
