I found through chrome dev tools that the custom.css.scss below wasn't being used in production. Does anyone know why heroku wouldn't use some scss?
my custom.css.scss for index page
/* Masters index */ .masters { list-style: none; margin: 0; li { overflow: auto; padding: 10px 0; border-top: 1px solid $grayLighter; &:last-child { border-bottom: 1px solid $grayLighter; } } } development index page

production index page

rake assets:precompile?
