Recently I am trying to modify the Andreas theme to suit my style. I made the main theme as black color. Everything looks fine to me - but not for smilies.

I discovered that once I changed the background to black color, there would be a box of white (or grey) surrounding the smilies - which is so odd. You may refer to the screen cap I attached or visit my site (http://www.timexplorer.com) to have a more clear idea on what I am saying (my English is not very good...forgive me pls~)

Anyone can figure out a solution on eliminating the white box (other than give up using smilies)? Many thanks for helping in advance~ ;)
