jquery - Making a header/menu bar for an off-canvas navigation menu fixed? -

i'm having trouble making element fixed off-canvas navigation design. http://codepen.io/stuffiestephie/pen/wajxxa

(resize viewport it's less 1000px, header isn't visible otherwise.) in desktop styles, nav bar fixed, in mobile header isn't though have !important declaration

	$(".toggle-nav").click(function() {      // calling function in case want expand upon this.      togglenav();    });            function togglenav() {  if ($('#drawer').hasclass('show-nav')) {    $('#drawer').removeclass('show-nav');          $('#nav-icon').removeclass('open');  } else {    $('#drawer').addclass('show-nav');       $('#nav-icon').addclass('open');  }  }    $('#closebutton').click(function() {    	  $('#drawer').removeclass('show-nav');    	  $('#nav-icon').removeclass('open');    });           	$("nav h3").click(function(){  		$("nav ul ul").slideup();  		if(!$(this).next().is(":visible"))  		{  			$(this).next().slidedown();  		}  	});      	$("#downsplasharrow").click(function(event) {        event.preventdefault();      if ($('header').is(":visible")) {          $('#site-canvas').animate({              scrolltop: $("#page-content").offset().top          }, 1000); } else {                    $('body').animate({              scrolltop: $("#page-content").offset().top          }, 1000);          }    }   );

this whole thing kinda convoluted fact header needs slide on rest of canvas when off-canvas menu drawer open.

any ideas?

edit: well, i've discovered rather troubling, jquery scroll-down function (desktop version) works in chrome not in firefox , ie! , in ie header fixed, not in chrome , firefox. ಠ_ಠ

try this:

move <header> in html outside of #site-canvas. html structure this:

<body>     <nav>     <header>     <#site-nav> 

then add css

nav.show-nav ~ header{     transform: translatex(300px); } 

next change css selector:

#drawer.show-nav, #drawer.show-nav + #site-canvas 

to this:

#drawer.show-nav, #site-canvas.slide 

now toggle new slide class here:

$(".toggle-nav").click(function() {     // calling function in case want expand upon this.     $('#site-canvas').toggleclass('slide');     togglenav();   }); 

i add padding-top:55px; #site-canvas give room fixed header.

see update codepen.
