Question

我正在尝试创建一个带有动画的汉堡包菜单。我尝试在 y 轴上添加变换，但它不会随着动画滑出。链接也有下划线。我添加了 text-decoration: none 但链接仍然有下划线。对于这两个错误，我在代码中做错了什么？

<template>
  <nav>
    <div class="brand">brandName</div>

    <ul class="nav-links" :class="'nav-links--' + isOpen">
      <li v-for="(list, $index) in navLinks" :key="$index">
        <a :href="list.link">{{ list.name }}</a>
      </li>
      <li id="button-part">
        <button>Hello</button>
      </li>
    </ul>

    <div @click="mobileNav()" class="burger">
      <i class="fa fa-bars"></i>
    </div>
  </nav>
</template>

<script>
export default {
  name: "HelloWorld",
  data() {
    return {
      current: 0,
      isOpen: "closed",
      navLinks: [
        {
          name: "Home",
          link: "/home",
        },
        { name: "About", link: "/about" },
        {
          name: "Contacts",
          link: "/contact",
        },
      ],
    };
  },

  methods: {
    mobileNav() {
      if (this.isOpen === "closed") {
        this.isOpen = "open";
      } else {
        this.isOpen = "closed";
      }
      console.log(this.isOpen);
    },
  },
};
</script>
