CODE Box in Vbulletin

hi everybody,

in vbulletin, when you use code tag, it will display a rectangular box around the code part.

But instead of box, i would like to display with dotted lines like in phpbb.

Can any one let me know how can i modify that part?

 

i figured it out after googling for some time.... topic can be closed.

 

If you shared your solution, you'd help somebody with same request looking.

 

for sure..... but how do i paste that whole template which i modified?
