Best to not switch away from the default (row) unless you really know what you're doing. Here's the guide I always consulted for flexbox direction help. I just consulted it until I got the feel for it. I could guess at what you're doing but I think this resource will be better than me hemming and hawing over what you're trying to do: https://css-tricks.com/snippets/css/a-guide-to-flexbox/
So some tips:
- column flips what the actual keywords of flex do (justify-content starts to act like align-items and visa versa).
- it's easier to develop for small screens and then expand up to large screens. This is because you already know what you'll have to expand from and you won't have to squish anything down. (I'm not saying you should restart your project though, this is a future tip only. Only restart if everything is truly fubar.)
