Need help with Keyboard Layout Editor

[manna]

Hello everyone,

I would like to order a custom Varmilo keycaps set. The problem is I don't like their font , and I don't know how to use a custom one on the Keyboard Layout Editor.
The font I'd like to use is Helvetica rounded with Italian legends.

Can someone please help me? Thanks.

Under the "Custom Styles" tab, I specified a custom font using:

Code: [Select]

@import url('https://fonts.googleapis.com/css?family=Source+Code+Pro');
* { font-family: 'Source Code Pro'; }
