汉堡不换成X

Question

我正在尝试创建一个汉堡包按钮，点击后会变成 ×。一切正常，我只是无法使 × 标志完美无缺。我想知道我应该翻译汉堡菜单顶部和底部栏的多少像素。我查了一些教程，他们做的和我做的一样，但由于某些原因我的不工作。

这是我的代码：

提前感谢您的帮助。

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");
  });
};

navSlide();

Answer 1

将 class="line 1" 中的名称更改为 class="line1"。东西很少... 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设为position: absolute:

  .hamburger div {
    position: absolute;
    width: 25px;
    height: 4px;
    background-color: #5b3b97;
    transition: all 0.3s ease;
  }

, 对每一行进行正确定位(.hamburger .line1 && .hamburger .line2 && .hamburger .line3):

  .hamburger .line1 {
    top: 0;
  }

  .hamburger .line2 {
    top: 50%;
  }
  .hamburger .line3 {
    top: 100%;
  }

最终旋转 135 度 transform: rotate(135deg); 并将前后位置设置为 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%;
  }
