【中文标题】响应式导航栏一旦打开就会阻止正文内容【英文标题】：Responsive navbar blocks body content once it's opened 【发布时间】：2022-01-16 07:39:11 【问题描述】：在您尝试制定解决方案之前，请确保您的 chrome 浏览器上启用了响应式工具栏。我正在尝试首先为移动设备制作响应式设计，然后再为桌面制作。但是我在打开汉堡菜单并且导航栏阻止我的内容时遇到了这个问题。我试图通过做 position: relative; 来解决这个问题。但我想让导航栏固定，所以当我滚动它时它就在那里。此外，当我在滚动时单击汉堡菜单时，它会回到顶部。请帮帮我

【参考方案1】：当您单击菜单时，它会跳到顶部，因为您的菜单是一个 a 元素。只需将其更改为 div：
<div class="toggle-button">
<span class="bar"></span>
<span class="bar"></span>
<span class="bar"></span>
</div>
为了在菜单打开时使内容可见，您可以在第一部分添加边距。您可以添加一个检查页面滚动的距离，以防止在向下滚动时打开菜单时添加和删除边距。将您的 .js 更改为：
const toggleButton = document.getElementsByClassName('toggle-button')[0]
const navbarLinks = document.getElementsByClassName('navbar-links')[0]
const firstSection = document.querySelector("section:first-of-type")
toggleButton.addEventListener('click', () =>
navbarLinks.classList.toggle('active')
firstSection.classList.toggle('marginTop');
)
window.addEventListener('scroll', function()
if(window.scrollY > 100)
firstSection.classList.add("scrolled");
else
firstSection.classList.remove("scrolled");
);
在您的 .css 中（过渡以使其更平滑）：
section:first-of-type
transition-duration: 1s;
section.marginTop:not(.scrolled)
margin-top: 200px;
【讨论】：
我需要另一个帮助。单击汉堡菜单时如何向导航栏添加过渡？ 您的菜单通过将显示设置为无/弹性来工作。显示属性上的转换 - 据我所知 - 不可能。不要改变显示，而是改变 max-height: .navbar-links width: 100%;最大高度：0；溢出：隐藏；过渡：最大高度 1s； .navbar-links.active 最大高度：200px; 当我点击菜单时，除了我们之前添加的边距外，现在什么都没有显示。 没关系，我不小心使用了“max-width”而不是“max-height”。有效。非常感谢，我的朋友！以上是关于响应式导航栏一旦打开就会阻止正文内容的主要内容，如果未能解决你的问题，请参考以下文章
