为什么我的下拉导航带有溢出：隐藏阻塞页面等于导航的高度？

Question

height blocking website这是在与手机大小相等的屏幕上工作时。我真的不知道如何让这个导航的高度不阻塞我网站的任何其他元素。例如，如果我向下滚动按钮所在的位置，由于导航的高度，即使它没有展开，我也无法单击它。

任何帮助或指点将不胜感激。

谢谢

编辑：我添加了一张图片来显示下拉高度如何阻挡网站的某些部分。一旦我向下滚动足够远，我就无法点击该按钮。

您的标题位置是固定的。这意味着标题之外的所有元素都将落在此标题的“下方”...

如果您可以制作一个真实世界的示例，那么了解您的问题可能会更好。

这是在标题上使用position: fixed 和在标题和导航上使用固定height 之间的混合。下面的示例或多或少可以解决您的问题。通过一些媒体查询和额外的逻辑，它应该适合你。

const revealNav = () => {
  const hamburger = document.querySelector('.hamburger');
  const nav = document.querySelector('nav');
  const navLinks = document.querySelector('.nav-links');

  hamburger.addEventListener('click', () => {
    hamburger.classList.toggle('is-active');
  }, false);

  hamburger.addEventListener('click', () => {
    navLinks.classList.toggle('is-active');
    nav.classList.toggle('is-active');
  });
}

revealNav();
