Looking for a specific spoiler tag code
 

I've seen many spoiler codes, but I'm looking for a specific one. The spoiler tag what this board is using.


The code simply places a "Spoiler:" before the text, and the text itself is the same color as the background, and only visible when highlighted. Also, it changes with the 2 alternating background colors. Any help would be very much appreciated!

I found one here that does just the one color.. perhase someone could tweak that for me?

post a screen shot, I know -I- can't be bothered to register at that board just to see your example...
