Membuat Efek Background Hujan Salju HTML

Bagi anda yang ingin mempercantik website atau blog, saya punya tips dengan menambahkan efek hujan salju yang cantik. Selain itu, warna dan ukurannya dapat diatur sesuai selera. Efek ini bisa berjalan sebagai background, sehingga anda tak perlu khawatir tulisannya tidak muncul atau turun tak karuan :D Oke langsung saja copy kan script berikut ke html anda

<script>
// Set the number of snowflakes (more than 30 - 40 not recommended)
var snowmax=30

// Set the colors for the snow. Add as many colors as you like
var snowcolor=new Array("#FF0000","#0000FF","#00FF00","#CC00FF")

// Set the fonts, that create the snowflakes. Add as many fonts as you like
var snowtype=new Array("Arial Black","Arial Narrow","Times","Comic Sans MS")

// Set the letter that creates your snowflake (recommended:*)
var snowletter="*"

// Set the speed of sinking (recommended values range from 0.3 to 2)
var sinkspeed=0.5

// Set the maximal-size of your snowflaxes
var snowmaxsize=27

// Set the minimal-size of your snowflaxes
var snowminsize=8

// Set the snowing-zone
// Set 1 for all-over-snowing, set 2 for left-side-snowing 
// Set 3 for center-snowing, set 4 for right-side-snowing
var snowingzone=1
