javascript - 汉堡按钮不在正确的位置

Question

我做了一个网站，它是移动响应的，带有一个粘性标题。但是在 Iphone 上，汉堡按钮不在正确的位置，并且也不能完美地与粘性标题一起移动。我不知道这是因为 Safari，但是，我没有在其他工具上遇到这个问题，只有在 iPhone 上。如果我在一个地方更改汉堡按钮的位置，它在另一部手机上看起来就不好看。

我不使用引导程序。我的问题是，我怎样才能让我的汉堡按钮在每部手机上都好看？

window.onscroll = function() {myFunction()};
            
var header = document.getElementById("myHeader");
var sticky = header.offsetTop;

function myFunction() {
  if (window.pageYOffset > sticky) {
  header.classList.add("sticky");
  } else {
  header.classList.remove("sticky");
  }
}

Answer 1

第一种方法

添加align-items: center;到导航标签。那是

nav{align-items: center;}

也删除top:20%;汉堡类。那是

.hamburger{top:20%}

position:fixed元素至少指定了top、left、bottom、right之一。

所以，这里对：5% 就足够了。

window.onscroll = function() {myFunction()};
            
var header = document.getElementById("myHeader");
var sticky = header.offsetTop;

function myFunction() {
  if (window.pageYOffset > sticky) {
  header.classList.add("sticky");
  } else {
  header.classList.remove("sticky");
  }
}

第二种方法

我们可以通过不翻译而不是添加将汉堡图标居中对齐

top:20%; 

计算为

top: calc((20vh - 30px) / 2); // header height = 20vh and hamburger height = 30px makes half of both to align middle of header

window.onscroll = function() {myFunction()};
            
var header = document.getElementById("myHeader");
var sticky = header.offsetTop;

function myFunction() {
  if (window.pageYOffset > sticky) {
  header.classList.add("sticky");
  } else {
  header.classList.remove("sticky");
  }
}

  margin: 0px;

  margin: 0;

  border-bottom: 1px solid var(--clr-accent);
