Có rất nhiều plugin để bạn tạo một slider cho trang webs của bạn trong wordpress. Và dĩ nhiên những slide ấy cũng rất chuyên nghiệp (nếu trả phí). Còn ở đây mình chỉ chia sẽ một cách gắn slider mà không phụ thuộc vào plugin thôi và nó cũng chỉ giới hạn trong phạm vi nào đó thôi.

Rồi tạo vào đó thư mục images để lưu trữ icon cho nút bấm qua trái và qua phải.
