A question about JuliaBox and themes

Hi all, I have recently started using Julia and JuliaBox and since I plan on sharing my findings with colleagues that might be interested in Julia I was wondering if I could do the same as with IPython notebooks and apply a css theme while also in JuliaBox, just to make it prettier for them to read (and honestly if I could use Fira Code instead of the default font for the code cells it would make my eyes so much much happier).

I mostly want to change fonts. Is this possible?

Thank you in advance.

I don’t think you can do that on Juliabox.
