Flex-box is a web concept though, that’s where it came from. The intention was always for `juce::FlexBox` to copy the CSS flex-box. @jules made a lot of comments about grid and flex-box around the time it was added to the web, and just before it was added in JUCE, for example:

I wanted the correct behaviour because I’ve been writing a module that simplifies UI development and discovered these issues when I was comparing CSS layouts to the equivalent JUCE ones.
