Menubutton is not responsive

Hi,

My responsive menu button is not working. Is something wrong in the following code?

<!– begin .header-mobile-menu –>
<nav class=”st-menu st-effect-1″ id=”menu-3″>
<div class=”btn-close-home”>
<button class=”close-button” id=”closemenu”></button>
” class=”home-button”><i class=”fa fa-home”></i>
</div>
<?php wp_nav_menu( array(‘theme_location’ => ‘primary’,’echo’ => true,’items_wrap’ => ‘

%3$s

‘)); ?>
<?php get_search_form( $echo = true ); ?>
</nav>
<!– end .header-mobile-menu –>

Thanks in advance!
