Effetto neve, un animazione molto carina, si puo'?

[Megadream]

Andando siu questo sito www.ufologia.net, si nota un animazione natalizia molto carina. Fiocchi di neve che scendono a ripetizione.

Sapete per caso se e' possibile trovare questo effetto e utilizzarlo sulla 2.2?

Thnks a lot
bye!

ciao ciao

ah dimenticavo è ovvio che devi caricare nella directory anche il file
fiocco.gif
ne basta uno ed ottieni l'effetto
scaricalo dal sito che hai mensionato acchiappandolo con tasto destro mentre scende........buon acchiappata
ti consiglio uno bianco

[Megadream]

Ehm ti ringrazio della info, ma non riesco a capire in che file devo mettere queste stringhe

per caso in index.php?

Inoltre quel file js devo ricrearlo io rinominando un file di testo o cosa?

thnks!

si esatto onload lo devi mettere nel body dell'index o sua altri file tipo l'index che so product_info

per il codice per il js si devi copiare il codice e metterlo su un file di testo e nominarlo con nome ed estensione .js

ciao

Anch'io ero interessato, provato e non funziona!!!
Inserito .js, modificato la index, copiato un fiocco.gif, ma niente da fare non scende sta benedetta neve...

un po' in ritardo...=)...
io ho provato questo script...funziona...l'ho inserito nell'header...
