Faire tomber de la neige
par Thibault1er Dim 27 Nov 2011 - 16:52
Bonjour,
L'hiver approche, et pour cela, je voudrais faire tomber de la neige sur le forum ou je suis administrateur. J'ai trouvé quelques codes Javascript, mais qui nécessitent de "déposer" plusieurs fichiers sur le forum, cependant je ne sais pas comment faire, de plus, je ne suis pas très fort en Javascript.
Donc, je vous demande de l'aide ; comment faire ?
Merci d'avance.

Merci beaucoup 
Sauriez-vous comment augmenter le nombre de flocons de neige qui tombe ? Car on peux sûrement mais il faut trouver où est la valeur dans ce code :
Edit : C'est bon, j'ai trouvé.
