You don't need the .ua-safari or .ua-ios here because this style is just
displaying the button itself. 

[juliandoucette, 2018/04/13 11:58:22]

There are two buttons. One for ua-safari, and another for ua-ios. That's why I
can't *just* use #content.safari (two would display instead of one).

Context: The browser name class without "ua" comes from the page name.

[ire, 2018/04/16 15:14:42]

Yes, but now neither button will show then the user visits the /safari page in a
browser that isn't Safari or iOS
