I have a question with two answers, that I had an open bounty on.
When I opened the site on mobile to award the bounty before time runs out, the
+100 buttons looked as if the bounty was already awarded to both answers.
However, on the desktop version of the website, the buttons aren't so opaque and seem to have a bit of transparency to distinguish them from an already awarded bounty.
I think on the mobile site the buttons should also have a bit transparency to signify a difference between an already awarded bounty, and bounty which is yet to be awarded.
