Ask HN: Favorite CSS / component framework for web admins?

I find myself about to build several administrative-type interfaces for a few different businesses. Similar stuff like create organizations / projects / users, view audit logs, things like this.

Do you have any favorite CSS or "fuller-stack" tools you reach for? I'm using Django (but not the Django admin) and would ideally prefer to just pull resources in from a 3rd-party CDN if possible (at least during dev.)
