I've been trying to find a decent BB code for a spoiler for a while, and I've finally got one running and thought I'd share the code.

<SPAN CLASS="spoiler" onmouseover="this.style.color='#FFFFFF';" onmouseout="this.style.color=this.style.backgroundColor='#000000'">&nbsp;{param}&nbsp;</span>

And the class for your CSS variables

.spoiler {COLOR: black; TEXT-DECORATION: none; background-color: black; font-weight: normal;}
