   - Khung: mềm, bo 14px, viền đồng mảnh, bóng nhẹ; rê chuột thì viền đồng đậm lên và nổi nhẹ.
   - Nút: viên thuốc; nút chính màu đồng chữ xanh mực; nút gửi tròn; chip và công tắc dạng viên thuốc.
   - Ô nhập: viền đồng mảnh, bo mềm, sáng viền khi gõ (giống khung hỏi trang đầu).
   - Văn bản soạn sẵn: tờ giấy có bóng đổ.
