So according to the Canvas HTML Whitelist, Flexbox is not a supported element. However, I have a few colleagues who are using flexbox in their work and it seems to be working for them. Does anyone know if Flexbox is officially supported by Canvas?
@swinning , I was able to find this conversation that includes a link to now-deprecated code for modifying global CSS: Flexbox Grid tips and guides. Is it possible that your school has implemented its own custom code so as to provide support for Flexbox in your school's instance?
