[Xin xỏ] Code tuyết rơi

[tieubao1504]

ACE cho hỏi có code nào giả lập tuyết rơi được ko vậy?

[tieulinh_huy_hp]

Code:

<script language="javascript" type="text/javascript" src="http://jishanvn.tk/noel/js/snow.js"></script>

cho code vào overheader thanks nhanh

cho code vào overheader thanks nhanh

Ấy lại dùng hàng của tớ rồi!

[tieubao1504]

sử dụng hình làm tuyết dc ko vậy?

[Tôn Ngộ Không]

Hình làm tuyết thì dùng code khác, nhưng sau nhiều lần dùng thấy rằng, dùng hình đôi lúc quá nặng gây load chậm cho các mem dùng pc cấu hình thấp, thêm nữa là hình thì to qua, hạt li ti nhìn nhẹ nhàn và dễ chịu hơn
Xem qua demo nhé:

có bạn ạ bạn mang hình lên mình làm cho nhưng ko thanks thì thôi nhá, có phần mềm làm ảnh này

[tieubao1504]

này bạn! cho nó rơi đi!

có cái đó đó

[KillAlt1.0]

Code:

#head{background:transparent url(http://i233.photobucket.com/albums/ee58/aznglitter/img/i14/14865.gif) center bottom;}
#bd{background:transparent url(http://i233.photobucket.com/albums/ee58/aznglitter/img/i14/14865.gif) center bottom;}

cho vào css

bạn tách lấy code ra dùm luôn đi!
