Forum Display Enhancements - Classic Style Snow Fall

This will give your site a classic holiday snow fall without any images, uploading any files, or adding any server load to your site.

It is also customize-able to fit your needs.


Classic Snow Fall

In your footer at the very end and below any other scripts you may already have there.

Add the following

<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

UPDATE 12-23-2011

Not a code update, but an optimized suggestion. As I know many of you will start using this on Christmas Eve.

Suggestion:

If you know your community has a lot of mobile web users, such as Apple iPod, setting the snow fall value count to 20 works best. (original value is 35).

// Set the number of snowflakes (more than 30 - 40 not recommended)
var snowmax=20

Happy Holidays


If you're tired of vBulletin you should upgrade to Woltlab Burning Board http://woltlab.com

All of my mobile users have a dedicated style they're automatically assigned to... They don't get to see the mean ol' snowflakes!

vBulletin 3 Patch Level 3 was seemingly the last version of vBulletin 3.

This work on it and all modern web browsers including Internet Explorer 10

If you have a lot of mobile web users, see notes added from last year above

[OldSchoolDSL]

Confirmed still working

Yes, even on modern browsers

[Nimchan]

Looks awesome! Thanks you =)

No longer supported as I no longer use vBulletin having moved to both WoltLab Burning Board and Invision Power Board.

I give 100% permission to reuse, modify, improve, enhance, and redistribute this code as freeware to anyone, everyone, and everywhere.

Good luck
