More updates coming soon!!!
This light theme is for those find it dazzling looking at white background. It is intended for the default three column layout, but you can also adjust the border for other layouts.
The code is quite messy at the moment, but posted here in case if everyone is interested.
This theme is modified from Joplin Clear UI theme by Marc Teyssier.
For installation, follow the custom css guide on Joplin and replace the corresponding code in 'userstyle.css' and 'userchrome.css'.
