Missing labels, bad contrast in pagination (likely inherited from django)
I've upped the contrast and fixed labels in a bunch of places in Postorius to improve our compliance with accessibility guidelines, but one place that's not fixed is the prev/next and "results per page" pagination inherited from django (for example, as seen on the list of lists page. The axe plugin for firefox accessibility checker says the "results per page" field needs an aria-label and the previous/next are too low contrast (likely because they're greyed out when disabled).
- prev/next may just not need to be displayed unless they're needed, rather than making them hard to read. (maybe can be changed in postorius)
- results per page needs an aria-label on the dropdown list (e.g. the one that says 10/25/50/100/200) (may need change in upstream django)
I'm working on the easier fixes within postorius for the pycon2018 sprint, so just filing this so it can be investigated at a later time.
