I'm making a webpage for my mums baking business (and to practice my novice coding skills, otherwise I'd just use a simpler solution rather than learning bootstrap).
I've got a header, then 3 bootstrap columns below it, one with an order form, one with images of her bakes, then one with links. I've sized them 3-6-3. I like the way the page looks fullscreen on my desktop but I want the columns to stack when browser gets smaller, or on another device. Currently they just smoosh together, the images get smaller, and after a certain point, a horizontal scrollbar appears. No stacking.
I'm sure I'm either trying to use bootstrap completely wrong, or there's a few glaring errors. I've been staring at it, and trying 'fixes' on here for so long, but I can't solve my issue. Some advice would be greatly appreciated.
one problem I know, is that the and aren't all formatted correctly, I can solve this myself with a bit of time, I just styled it whilst I had it wrongly formatted and when I do it correctly it all looks ugly again, so I'm leaving it for another day. My main problem is the stacking issue.
