固定画布外导航菜单的标题/菜单栏？

Question

我无法通过画布导航设计来固定元素。 http://codepen.io/StuffieStephie/pen/wajxXa

（调整视口的大小，使其小于1000像素，否则将不显示标题。）在桌面样式中，导航栏是固定的，但即使在移动设备中，即使我有！important声明，标题也不会固定

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

整个事实有点令人费解，因为在打开非画布菜单抽屉时页眉需要与画布的其余部分一起滑过。

有任何想法吗？

编辑：好吧，我发现了一些麻烦的地方，我的jQuery向下滚动功能（台式机版本）可在Chrome中使用，但不能在Firefox和IE中使用！ 在IE中，我的标头是固定的，但在Chrome和Firefox中不是。 这是什么ಠ_ಠ

Answer 1

尝试这个：

将HTML中的<header>移到#site-canvas 。 因此，您的HTML结构如下所示：

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

然后将此添加到您的CSS

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

接下来更改此CSS选择器：

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

对此：

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

现在在这里切换新的slide类：

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

我还要添加padding-top:55px; 到#site-canvas为您的固定标题#site-canvas出空间。
