I was actually using that. What I don’t get is why div, when defined as a flex column with a background color of light green, shows nothing at all, I would have expected a light green column taking up 100% of the page.
Edit: Basically I don’t understand how to apply what I’ve read to what I’m trying to do.
Alright, I’m starting to get it. It won’t show a column without content. Is flexbox the right tool for making an empty vertical column in css? Do I need to use grid? Or if I can use flexbox, one thing that I’m finding difficult is how to put the columns side by side, though I believe I saw a tutorial for that.
