But, this will load only my own jquery-ui file? Or both files?
Anyway, it’s cool to keep your CSS files with your base components working, the problem appears when there is other sections (even URLs with no UM Components) that are using jQuery UI Components. This second group is getting styled by UM CSS files, when they’re totally different.
It’s doable to add some prefix to your jQuery UI Components? Like the datepicker, for example… So we can use your datepicker in the user profile and a new datepicker in other part of the web with different styles without overrides.
