I am missing something, I guess !
As soon as i insert app.use(plugins.Theme); in my start script, i get the error message : Cannot read property 'className' of null.
I didn't find anything in the docs nor the forum.
Any suggestion welcome.
Could you please share you app creating code? I guess we need more details.
The theme plugin does no magic. It sets CSS to document body
https://github.com/webix-hub/webix-jet/blob/master/sources/plugins/Theme.ts#L30 and inside the webix.html.removeCss/addCss functions its modifies document.body.className. This should be available for sure.
