固定畫布外導航菜單的標題/菜單欄？

Question

我無法通過畫布導航設計來固定元素。 http://codepen.io/StuffieStephie/pen/wajxXa

（調整視口的大小，使其小於1000像素，否則將不顯示標題。）在桌面樣式中，導航欄是固定的，但即使在移動設備中，即使我有！important聲明，標題也不會固定

  $(".toggle-nav").click(function() { // Calling a function in case you want to expand upon this. toggleNav(); }); function toggleNav() { if ($('#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); } } );

整個事實有點令人費解，因為在打開非畫布菜單抽屜時頁眉需要與畫布的其余部分一起滑過。

有任何想法嗎？

編輯：好吧，我發現了一些麻煩的地方，我的jQuery向下滾動功能（台式機版本）可在Chrome中使用，但不能在Firefox和IE中使用！ 在IE中，我的標頭是固定的，但在Chrome和Firefox中不是。 這是什么ಠ_ಠ

Answer 1

嘗試這個：

將HTML中的<header>移到#site-canvas 。 因此，您的HTML結構如下所示：

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

然后將此添加到您的CSS

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

接下來更改此CSS選擇器：

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

對此：

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

現在在這里切換新的slide類：

$(".toggle-nav").click(function() {
    // Calling a function in case you want to expand upon this.
    $('#site-canvas').toggleClass('slide');
    toggleNav();
  });

我還要添加padding-top:55px; 到#site-canvas為您的固定標題#site-canvas出空間。
