为什么这个部分在悬停时表现得很奇怪？

Question

这是我通过观看 youtube 视频制作的侧边导航栏文件，我在其中调整了一些东西，它工作正常，但有一个小问题。每当我将鼠标悬停在底部的个人资料信息框上时，它就会开始跳舞。为什么？

let arrow = document.querySelectorAll(".arrow");
for (var i = 0; i < arrow.length; i++) {
  arrow[i].addEventListener("click", (e) => {
    let arrowParent = e.target.parentElement.parentElement; //selecting main parent of arrow
    arrowParent.classList.toggle("showMenu");
  });
}

let sidebar = document.querySelector(".sidebar");
let sidebarBtn = document.querySelector(".bx-menu");
console.log(sidebarBtn);
sidebarBtn.addEventListener("click", () => {
  sidebar.classList.toggle("close");
});

Answer 1

固定位置似乎给 backdrop-filter 带来了问题。尝试替换：

.sidebar .nav-links li:hover{
 backdrop-filter: blur(40px);
box-shadow: 10px 0 15px rgba(0,0,0,0.1);

}

与：

.sidebar .nav-links li:hover:not(.sidebar .nav-links li:last-child){
 backdrop-filter: blur(40px);
box-shadow: 10px 0 15px rgba(0,0,0,0.1);}

}
