   .et-header           : toàn bộ phần đầu trang

   .et-benefits         : khu vực quyền lợi mua hàng
   .et-footer           : chân trang

   LƯU Ý:
   - CSS nằm phía dưới sẽ được ưu tiên nếu selector có cùng độ ưu tiên.
   - Các chỉnh sửa riêng nên đặt ở mục "TÙY CHỈNH NHANH" cuối file.
   - gap        = khoảng cách giữa các phần tử.
   - font-size  = cỡ chữ.
   - padding    = khoảng cách bên trong phần tử.
   - margin     = khoảng cách bên ngoài phần tử.
