Can I change css of spoiler?

I can change css of "quote" and "code", but I dont know where spoiler css is.
Can I? and how to if I can?

Search for spoiler.

Code:

   
.spoiler {
   margin: 8px;
   padding: 8px;
   }
.spoiler dt {
   display: block;
   margin: -8px -8px 8px -8px;
   padding: 3px;
   font-weight: bold;
   font-size: 11px;
   text-transform: uppercase;
   }
.spoiler dd {
   padding: 8px;
   }


You will get something similar.

Thank you so much. Invision css has .spoiler , but phpBB2 and 3 don't.

I found other interesting thing :

Code:

.spoiler {
    border-top: 2px dashed #6698FF;
    border-right: 2px dashed #6698FF;
    border-bottom: 2px dashed #6698FF;
    border-left: 2px dashed #6698FF;
    background-color: #e1ebf2;
    }

You will make border dash with color.

Is it solved then?

Yes, it is. Thank you!
