/*
  ルールズの見た目(JS が無くても効くものだけ)。
  JS があるときだけ使う部品(読み上げ・文字サイズのボタン、アニメーション)の見た目は rules.js の中にあります。

  【古いブラウザ(IE等)でも読めることを先に守ること】
  - 見た目は div と class に付けます。main・nav・section などの HTML5 の要素には付けません(IE8 以前は当てられません)。
  - 色は先に単色で書き、その下に rgba・グラデーションを重ねます(読めないブラウザは単色のまま)。
  - 並べ方は inline-block と float までにします。flex・grid は @supports の中だけで使います。
  - CSS の変数(var)は使いません(IE は読めず、色がまるごと抜けます)。
  色: 背景 #050b12(濃紺)/ 黄緑 #a6ff00 / 水色 #00e5ff / 文字 #e6f6ff
