Thanks mọi người đã quan tâm. :D
Hum nay mình vào trường thực hành cũng bị ngay trường hợp này vơi trình duyệt FireFox, sau khi hỏi bạn thì bạn thử mở với IE (bản cũ) thì lại ko có. Vè nhà thì mình thử mở với trình duyệt IE bản mới nhất thì vẫn bị :( thử lấy bài tập của bạn để vào vẫn bị, rùi bản thân tự làm 1 bài khác nữa , lần này rất cẩn thận nhưng khi xem vẫn bị. Chắc có lẽ là do trình duyệt nhỉ :-?
Up nguyên đoạn code copy nguyên si từ Dreamweaver cho mọi người xem nè.Phần in đậm là phần mình làm đó, mấy cái còn lại là Dreamweaver nó tự tạo , để vậy cho mọi người dễ nhìn :( Để hum nào thử làm bằng notepad xem có bị vậy ko.
