css: move CSS declarations above nested rules

The new SASS version warns that decelerations should appear above nested
rules. This change should not have any visual impact.

> ▲ [WARNING] Sass's behavior for declarations that appear after nested
rules will be changing to match the behavior specified by CSS in an upcoming
version. To keep the existing behavior, move the declaration above the nested
rule. To opt into the new behavior, wrap the declaration in `& {}`.
