ဒီတစ္ခါ snow effect ကို ပံုမပါပဲနဲ႔ သံုးလို႔ရမယ့္ JavaScript ေလးပါ။ ေလးတဲ့ ဆိုက္ေတြမွာ သံုးရင္ အဆင္ေျပမွာပါ။ သံုးလို႔အဆင္ေျပမယ့္ IE ေတြကေတာ့ ie6, ie7, firefox ေတြပါ။ က်န္တာနဲ႔ေတာ့ အဆင္ေျပမယ္ မထင္ပါဘူး။ အသံုး၀င္မယ္ေတာ့ ထင္ပါတယ္။ သူက .js ဖိုင္ကို သပ္သပ္လုပ္ပါ။ ၿပီးမွ ကိုယ္ေရးတဲ့ Page မွာထည့္ၿပီး သံုးႏိုင္ပါတယ္ခင္ဗ်။

ဒါကေတာ့ .js ဖိုင္ရဲ႕ source code ပါ။

အဲဒါၿပီးရင္ ကိုယ္ေပၚေစခ်င္တဲ့ Page ရဲ႕ Body Tag ထဲမွာ အေကာင္းဆံုးကေတာ့ ေအာက္ဆံုးပိုင္းေလာက္မွာ ထည့္ပါ။
