/* =====================================================================
   台東包棟民宿網｜最新消息版面
   來源：news 資料夾原型 news.css。主內容的視覺規則完整沿用，
   差別只有三點：
   1. 全部收進 .bdn 命名空間。原型的 body、a、img{width:100%} 是全域規則，
      直接載入會把全站導覽列的 logo、頁尾圖片一起撐滿。
   2. 補上對舊站全域 CSS 的還原：舊站有 *{margin:0;padding:0}、a{display:block}、
      h1{font-size:15px;color:#777}、body{letter-spacing:1px;line-height:30px}。
   3. 原型 8～11px 的內文字級在手機上過小，可讀文字略為放大；裝飾用英文小標維持原樣。
   原型自帶的頁首頁尾（.site-header/.site-footer）不使用，改用全站共用導覽列與集團頁尾。
