This widget creates an animated themed ACKspace logo.

Created by xopr

Using this widget

To insert this widget, use the following code: 

{{#widget:Logo
|image=/w/images/e/e9/ACKsmass_logo.png
|width=600px
|height=200px
|padding=8px
|float=right
}}

This will give the following result:

Notes

  • it will display snow in December - March and will show Christmas lights between 7 December and 7 January
  • image is mandatory, the rest is optional.
    it also must be written without protocol since colon (:) is not allowed, and may be relative, for example: //ackspace.nl/w/images/e/e9/ACKsmass_logo.png or /w/images/e/e9/ACKsmass_logo.png
  • You must provide a unit for the sizes (i.e. px, %, etc.)
