Change appearance for secondary Nav without Primary nav

I just created a secondary Nav to place in the Footer and its work.
The problem that menus are displayed vertically i want to display a horizontally .
as indicated by the Screen Shot
(SC Befor to the SC after) . without changing the primary nav
the link for my web site:
i have a demo account:
username: demo
password: demo

this is the funtion in fuction.php:

    'secondary' => __('Secondary Menu', 'vertulab'),

Here is the code in the page:

<div id="karibu-navigation">		

		<?php wp_nav_menu( array('theme_location' => 'secondary',) ); ?>


here is the CSS

#karibu-navigation {
	background: #ffffff;
	color: #4D4D4D;
	margin: 1px 10px;
	text-align: center;
	text-shadow: #fafafa 1px 1px 0;
	display: inline-block;
    width: 100%;
    text-align: center;
