I have now managed to fold in / out many attempts with the tpl and css which I was not familiar with but simply tried a lot and it also works well with the thickness of the inner lines and curves .... etc

PHP Code:

#shoutbox .panel {border-left: solid 1px rgba(0,0,0,0.1); }
#shoutbox .panel {border-right: solid 1px rgba(0,0,0,0.1); }
#shoutbox .panel {border-bottom: solid 1px rgba(0,0,0,0.1); }

#shoutbox .window {border-radius: 0px 0px 5px 5px; border: solid 1px rgba(0,0,0,0.05); overflow-y: scroll; }
