Adding Custom Themes to Akomi
The CSS file in /var/www/akomi/www/style/style.css is the base style for the whole Akomi experience. That is the Light Theme in the Admin section. You can create and edit your own css file to extend and change that base theme with your own style, colors, fonts, etc.
Once you have created your custom theme you should install it in:
Then in /var/www/akomi/config/custom_environment.ini you need to edit the custom layout section.
customstyles = "Light Theme|,Dark Theme|dark_theme.css"
Here, you'd edit his and add your theme:
customstyles = "Light Theme|,Dark Theme|dark_theme.css,Custom Theme|custom_theme.css"
Next time you go to add or edit a user your new theme will be available as an option.
