Input boxes truncated due to “width” rules in admin.css

Thanks for a great plugin! It does just what we need.

I would like to request one small improvement. When editing the “Expire Date” “On” field, the text is truncated:

When I remove this CSS in expire-users/css/admin.css:

#expire_user_date_on_dd,
#expire_user_date_on_hrs,
#expire_user_date_on_min {
	width: 30px;
}

#expire_user_date_in_num,
#expire_user_date_on_yyyy {
	width: 40px;
}

the fields look fine:

So my request would be to either remove this CSS or at least change “width” to “min-width” so it doesn’t truncate text.

Thanks!
