Thank you for the reply.
I’ve followed the instructions at given links, but it seems that it doesn’t work. Maybe I’m too noob for this 
Here’s what I’ve did in my styles.scss:
[code]
@include font(“Open Sans”, ‘…/…/…/…/expenseplannertheme/fonts/OpenSans-Light-webfont’);
$v-font-family: “Open Sans”;
@import “expenseplannertheme.scss”;
@import “addons.scss”;
// This file prefixes all rules with the theme name to avoid causing conflicts with other themes.
// The actual styles should be defined in expenseplannertheme.scss
.expenseplannertheme {
@include addons;
@include expenseplannertheme;
}
[/code]And here’s what gives me theme compilation:
