Trying to customize colors without breaking npm use, I copied rc-easyui/dist/themes/material to scr/css and changed my index.css
/*@import '~rc-easyui/dist/themes/material/easyui.css';*/
@import 'css/easyui.css';
this works when I run it (react-scripts start) but when I build and deploy most UI elements are not visible, but if I inspect that page I see they are there. switching back to @import '~rc-easyui/dist/themes/material/easyui.css'; and build again restores everything. I haven't even edited any files yet, this is just copying the folder. what am I missing?
