vote 2 down vote accepted  You can do this by using the
SecurityTrimmedControl in your masterpage or pagelayouts in the
<head> tag.   <Sharepoint:SPSecurityTrimmedControl
runat=”server” Permissions=”ViewPages”> <!-- CSS for external
users --> <Sharepoint:SPSecurityTrimmedControl runat=”server”
Permissions=”FullMask”> <!-- CSS for admin users -->
