我正在尝试创建一个汉堡包按钮，单击后该按钮将变为×。一切都很好，我就是不能把×符号做成完美的形状。我想知道我应该翻译多少像素的汉堡菜单的顶部和底部栏。我查了一些教程，它们和我做的一样，但我的一个赛季不起作用。
这是我的代码：
感谢您提前提供的帮助。
const navSlide = () => {
const hamburger = document.querySelector(".hamburger");
const nav = document.querySelector(".nav-links");
const navLinks = document.querySelectorAll(".nav-links li");
hamburger.addEventListener("click", () => {
//Toggle
nav.classList.toggle("nav-active");
//Animate
navLinks.forEach((link, index) => {
if (link.style.animation) {
link.style.animation = "";
} else {
link.style.animation = `navLinkFade 0.5s ease forwards ${
index / 7 + 0.5
}s`;
}
});
//hamburger animation
hamburger.classList.toggle("toggle");
});
};

</html>class="line 1"中的名称更改为class="line1"。几乎没有什么。。。将您的.hamburger声明为position: relative;，并给出width和height:
.hamburger {
position: relative;
display: none;
cursor: pointer;
width: 25px;
height: 20px;
}
比，.hamburger div设置为position: absolute:
.hamburger div {
position: absolute;
width: 25px;
height: 4px;
background-color: #5b3b97;
transition: all 0.3s ease;
}
，为每条单行(.hamburger .line1 && .hamburger .line2 && .hamburger .line3(做出正确的位置：
.hamburger .line1 {
top: 0;
}
.hamburger .line2 {
top: 50%;
}
.hamburger .line3 {
top: 100%;
}
最后旋转135度transform: rotate(135deg);，并在设置之前和之后定位顶部，如top: 50%;和中线定义display: none;:
.toggle .line1 {
transform: rotate(-135deg);
top: 50%;
}
.toggle .line2 {
display: none;
}
.toggle .line3 {
transform: rotate(135deg);
top: 50%;
}
