Could you tell me why the navian-theme-styles.css file goes back to the original without me doing anything?
The file has been modified and I am forced to re-upload it each time.
Thank you for your help
This was caused by that navian-theme-styles.css file is automatically generated based on the theme settings (Fonts, Color, Menu style,..) in your Dashboard > Appearances > Customize, so please do not modify that file.
If you want to customize or adding CSS code, please add your CSS code into your Dashboard > Appearances > Customize > Addition CSS.
Or you can add it into the themes/navian/style.css file.
