</style>

Bạn nên tải về file js lighwindow.js sau đó upload lên host hoặc lên googlecode để sử dụng cho blogspot của bạn.

Lưu Template.

Bước 2. Thiết lập cấu trúc HTML cho các liên kết như sau:

<a class='lightwindow' href='#' params='lightwindow_width=600,lightwindow_height=600,lightwindow_loading_animation=true' rel='nofollow' title='Title Text'>Text Link</a>

Chú ý điều chỉnh width (600) và height (600) tương ứng với chiều rộng và chiều cao của cửa sổ hiệu ứng sao cho tương thích với từng trường hợp áp dụng.
