Close responsive menu on pageload

Question

I created a responsive navigation menu, but for some reason I can't get it to start out closed.

If you look at the website here http://riprap.pdslo.com and re-size your screen to a phone or tablet size, then hit refresh you will see that it is open on page load.

Here is the code if anyone would like to take a stab at it and try to get the menu to close on page load. (I apologize for the code dump, just not sure where I went wrong.)

I would greatly appreciate any help.

-----HTML Code-----

<nav id="menu-wrap">    
    <ul id="menu">
<li><a href="http://<?php echo $_SERVER['SERVER_NAME']; ?>/#">Home</a></li>
<li>bla bla</li>


    </ul>
</nav>

-----JS Code-----

        <script type="text/javascript">
$(function() {
        if ($.browser.msie && $.browser.version.substr(0,1)<7)
        {
        $('li').has('ul').mouseover(function(){
            $(this).children('ul').css('visibility','visible');
            }).mouseout(function(){
            $(this).children('ul').css('visibility','hidden');
            })
        }

        /* Mobile */
        $('#menu-wrap').prepend('<div id="menu-trigger">Menu</div>');       
        $("#menu-trigger").on("click", function(){
            $("#menu").slideToggle();
        });

        // iPad
        var isiPad = navigator.userAgent.match(/iPad/i) != null;
        if (isiPad) $('#menu ul').addClass('no-transition');      
 });      
 </script>

-----CSS Code-----

    /* Mobile */
    #menu-trigger {

        #menu .top-list{display:none;}

Answer 1

In line 140 (the last part) of the css you have to add following:

#menu { display:none; }

So the menu is hidden in the beginning on screens lower than 767px.
