Good code but I went with another spoiler code. I'll use it if someone can tell me how to add a border and a gray shading to the spoiler box/contents.

[godkillah]

that can be done with css i suppose
a simple example is

<style>
.spoiler div{
border:ridge;
border-bottom-color:#999999;
border-top-color:#999999;
border-left-color:#999999;
border-right-color:#999999;
border-bottom-width:thin;
border-top-width:thin;
border-left-width:thin;
border-right-width:thin;
}
</style>

thank you all for comments
