/* Website công khai của trung tâm đào tạo và sát hạch lái xe.
   Màu sắc và kiểu chữ CỐ ĐỊNH tại đây (quản trị không chỉnh): xanh lá của logo, chữ đậm trên nền sáng, chữ trắng trên nền xanh,
   mọi cặp chữ và nền đều đạt tương phản tối thiểu 4,5:1. Website chỉ có một giao diện sáng, không đổi theo chế độ tối của máy khách.
   Điểm nhớ của thiết kế: đầu trang con và khối đăng ký tư vấn làm như biển chỉ đường xanh có viền trắng mảnh bên trong;
   vạch kẻ đường vàng nét đứt chỉ dùng làm gạch chân tiêu đề và gạch đầu dòng. Phần còn lại giữ yên tĩnh, thoáng, bo góc lớn. */
