Custom font within user CSS.

[ThomasLeigh]

I wonder would it be possible to allow incorporating custom font within user CSS? I’ve tried with

@import url('https://fonts.googleapis.com/css?family=Lato:300&subset=latin-ext');

and then to refer to this font within further CSS, but it seems not to be working currently.

why not use local fonts ? Maybe it's better to prevent foreign request to keep device secure.
