I written this code to hide admin bar from my theme

<?php global $user_ID; if( $user_ID ) :  if( current_user_can('level_10') ) : show_admin_bar(true); else : {  show_admin_bar(false); } endif; endif;
?>

after it is showing blank strip above body to remove that i modified above code

<?php global $user_ID; if( $user_ID ) :  if( current_user_can('level_10') ) : show_admin_bar(true);
		 else : {  show_admin_bar(false); echo '<style type="text/css" >#wpadminbar{display:none; visibility: hidden;}</style>'; } endif; endif;
		?>

but is also giving me same result
