漢堡按鈕不在正確的位置

Question

我制作了一個網站，它是帶有粘性標題的移動響應式網站。 但是在 iPhone 上，漢堡按鈕不在正確的位置，並且也不能完美地與粘性標題一起移動。 我不知道這是因為 Safari，但是，我沒有在其他工具上遇到這個問題，只有在 iPhone 上。 如果我在一個地方改變漢堡按鈕的位置，它在另一部手機上看起來不太好。

我不使用 Bootstrap。 我的問題是，我怎樣才能讓我的漢堡按鈕在每部手機上都好看？

 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

第一種方法

添加align-items: center; 導航標簽。 那是

nav{align-items: center;}

同時去除top:20%; 在漢堡班上。 那是

.hamburger{top:20%}

position:fixed元素至少分配top, left, bottom, right 之一。

所以，這里正確：5% 就足夠了。

 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"); } }

第二種方法

我們可以通過不翻譯而不是添加將漢堡圖標對齊到中心

top:20%; 

計算為

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"); } }
