Changing box width/height on container resize

My boxes are "size63" and "size33". My last container resize makes my container smaller than these boxes and they get cut off - which causes my browser to freeze up and crash.

Does anyone have any ideas on how I could resize or change these box sizes to fit within my container and still have them order nicely in the container?

Did you find anything on the subject? I'm trying to achieve the same.

You might want to check #23

@jchatard thank you for for #23, this could definitely work out! I didn't end up finding any solution besides making sure I had the container that contained nested not get smaller than the largest box so it wouldn't crash. Then used viewport to make sure it played "alright" in mobile.
