Is Soma offerring some sort of Universal Support? - JayPanoz/Soma GitHub Wiki

Alright, you want to know if this stylesheet is likely to save your arse absolutely everywhere?

Not. Even. Close.

I can’t guarantee Soma is bulletproof since a lot of ePub apps don’t even fully implement ePub2 specs–I’m looking at you, Android apps… Die, Die, DIE!

Listen, some apps don’t even support some tags (e.g. hr, mark, &c.) because their developers don’t give a damn about standards. Others don’t even support CSS and I’m not kidding.

So if some readers complain, tell them to use another app, a better one. And if you want to publicly shame bad apps, rest assured I won’t stand in your way–Yeah, that guy far away, cheering you on, that’s me.
