Question

This is the function im doing, the only thing I want to change is have the snow appear BEHIND everything; so its not on top of divs and whatnot; I just want it to appear in the background of everything. Here is the code.

    <script type="text/javascript">
    // Set the number of snowflakes (more than 30 - 40 not recommended)
    var snowmax=35

    // Set the colors for the snow. Add as many colors as you like
    var snowcolor=new Array("#aaaacc","#ddddff","#ccccdd","#f3f3f3","#f0ffff")

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

    // 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=0.6

    // Set the maximum-size of your snowflakes
    var snowmaxsize=30

    // Set the minimal-size of your snowflakes
    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

Change

snow[i].style.zIndex=1000

set it to

snow[i].style.zIndex=-1;
