# Gives `<body>` a right padding in the width of a scrollbar.
# Also gives elements anchored to the right side of the screen
# an increased `right`.
#
# This is to prevent the body and elements from jumping when we add the
# modal overlay, which has its own scroll bar.
# This is screwed up, but Bootstrap does the same.
