What is worng with this code?

Hi folks. I’m a newbie. I try to have a fixed footbar witch only shows up when its not showed on a mobile device. As you can see i use the wp_is_mobile() function. But i do something wrong. It ignores the wp_is_mobile() and the footbar shows up on a mobile.

Can somebody help me with this?

<?php
/**
 * The template for displaying the footer.
 *
 * Contains the closing of the #content div and all content after
 *
 * @package Oblique
 */
?>

        </div>
    </div><!-- #content -->

    <div class="svg-container footer-svg svg-block">
        <?php oblique_svg_1(); ?>
    </div>
    <footer id="colophon" class="site-footer" role="contentinfo">
        <div class="site-info container">
            <?php do_action('oblique_footer'); ?>
        </div><!-- .site-info -->
    </footer><!-- #colophon -->
</div><!-- #page -->

<?php wp_footer(); ?>

if (wp_is_mobile()) { 

} else {

<div class="fixedBar">
<div class="boxfloat">
