I would like to suggest a idea about styling an app/website made in Mendix. It is very hard to make a custom style website in Mendix. In the Mendix Studio Pro editor, you can only edit like colors and size, but that's it. Something like background-image or hover is not even possible and if it is possible, it's so hard to find a clear tutorial on the platform. For me as a UX designer it's a bit frustrating. Maybe I am looking at the wrong things.
I am following the Style your App with CSS learning path, but it is outdated and some things don't work anymore. There is very little to be found about customizing in the Docs and on the Forums. is it possible to check this learning path and rewrite it to the newest Mendix version?
