> your user styles can override the developer's (and the browser's) styles on a per-site basis.
Too bad Mac Safari is the only browser of significance that still has an interface to load a user style sheet.
Yes, other browsers have extensions for using them including separate ones for separate sites but how many people really want to create and manage those, especially on mobile?
so what the parent wishes for is what you should be wishing for too (that is, to be able to style all form controls).
