Is it possible to have a stylesheet that would check for the current operating system and change the font accordingly, or possibly just have TiddlyWiki choose a different stylesheet based on the operating system? If so, how would I go about that?
The reason I'm asking is because I'm have heavy Quine app user for iOS, but iOS has a limited selection of fonts compared to Mac OS. I'd like to have a particular font in my stylesheet unique to my MacBook and another font chosen for iOS.
