Image Background CSS - Sunbird 0.2

Advanced Tip: Calendar Grid Background Image

/* CalendarGridBackgroundImage.css

   To add a personal background image to all calendar grid views,
   save this css in your profile [1] chrome directory,
   import this CSS in your userChrome.css [2],
   add your image, and modify the url.

   For Sunbird, the userChrome.css path may be something like the following
   w2k: c:\Documents and Settings\USER\Application Data\Mozilla\Sunbird\Profiles\NNNNN.default\chrome\userChrome.css
   gnu/linux: ~/.mozilla/sunbird/NNNNNN.default/chrome/userChrome.css

   1. Save this file in your profile as chrome/CalendarGridBackgroundImage.css
   2. Add the following to profile file chrome/userChrome.css (create if none):
     @import url("CalendarGridBackgroundImage.css");

   3. Put the desired background image in the same directory.
   4. Modify the url in CalendarGridBackgroundImage.css to the image filename.

   The CSS was tested on Sunbird 0.2rc1 and 20041217-cal on Mozilla 1.7.5.
   It is likely to require changes for future versions. 

   Warning: using userChrome.css can lead to errors developers can't reproduce.
   Test with userChrome.css removed before reporting Sunbird/Calendar errors.
