Shows, HELP! Options

[ZeT0]

How do I put :
border-bottom: 1px dotted dimgray;
On the shows section on a myspace music profile.
Also, how do I change the width of it all?

I can't even see my shows when I put that code on.

EDIT:Scrap that, worked fine.
Though, with my music player, it changes the size of the twitters ( I havn't put them on yet, but I know it does it )
I changed :

CODE

object {position:absolute; height:345px; width:450px; left:50%; z-index:4;}
object {top:1337px!important; margin-left:-43px!important;}
object object, td td td object, embed {position:static; margin:auto!important;}

To :

CODE

object {position:absolute; height:345px; width:450px; left:50%; z-index:9;}
object {top:1337px!important; margin-left:-43px!important;}
object object, td td td object, embed {position:static; margin:auto!important; height:auto; width:auto;}

But THEN the player doesn't even show up.
