Hello,
Apologies for the Inconvenience regarding this.
Since the css/font-icons.css File does not need any SCSS Codes, we did not add this file in the sass/ Folder as you can add this File directly to HTML. However, if you want to generate it using SASS, you can simply add this File in the sass/ Folder and then change the extension to scss. Then simply add this Line of Code:
[ch_pre]@import "sass/font-icons.scss";[/ch_pre]
at the bottom of the style.scss File.
This will definitely work fine. We will fix this in the next update. Hope this Helps!
