Question

我需要制作一个侧面导航菜单

我到目前为止有什么：

function toggle() {
  document
    .querySelector('.nuxt-link-exact-active')
    .classList.remove('nuxt-link-exact-active')

  event.target.classList.add('nuxt-link-exact-active')
}

.default-layout {
  background: purple;
  min-height: 100%;
  display: grid;
  grid-template-columns: 230px 1fr;
}
main {
  background: #000;
  border-radius: 0.9rem;
  margin: 1.5rem 2rem 1.5rem 0;
  padding: 2rem;
}
nav ul {
  display: grid;
  grid-gap: 1rem;
  justify-content: center;
  padding: 5rem 0;
  grid-template-columns: 100%;
  padding-left: 2rem;
  list-style: none;
}
nav ul li .nav-item {
  cursor: pointer;
  color: #fff;
  display: block;
  padding: 1.5rem;
}
nav ul li .nav-item.nuxt-link-exact-active {
  background: #000;
  border-top-left-radius: 10px;
  border-bottom-left-radius: 10px;
}

<div class="default-layout">
  <nav>
    <ul>
      <li>
        <a class="nav-item nuxt-link-exact-active" onclick="toggle()"
          >Menu 1</a
        >
      </li>
      <li>
        <a class="nav-item" onclick="toggle()">Menu 2</a>
      </li>
      <li>
        <a class="nav-item" onclick="toggle()">Menu 3</a>
      </li>
      <li>
        <a class="nav-item" onclick="toggle()">Menu 4</a>
      </li>
    </ul>
  </nav>
  <main>
    <p>content</p>
  </main>
</div>

我需要的外观，但没有成功：

除了这种外观外，我还需要在项目之间导航时使用效果，但是我不知道该怎么做，这里有一些我想要的平滑效果示例：

我现在做造型。以后再添加动画效果。

Answer 2

尝试一下

function toggle() {
  document
    .querySelector('.nuxt-link-exact-active')
    .classList.remove('nuxt-link-exact-active')

  event.target.classList.add('nuxt-link-exact-active')
}

.default-layout {
  background: purple;
  min-height: 100%;
  display: grid;
  grid-template-columns: 230px 1fr;
}
main {
  background: #000;
  border-radius: 0.9rem;
  margin: 1.5rem 2rem 1.5rem 0;
  padding: 2rem;
}
nav ul {
  display: grid;
  grid-gap: 1rem;
  justify-content: center;
  padding: 5rem 0;
  grid-template-columns: 100%;
  padding-left: 2rem;
  list-style: none;
}
nav ul li .nav-item {
  cursor: pointer;
  color: #fff;
  display: block;
  padding: 1.5rem;
    transition: width 300ms;
  width: 120px;
  float: right;
}
nav ul li .nav-item.nuxt-link-exact-active {
  background: #000;
  border-top-left-radius: 20px;
  border-bottom-left-radius: 20px;
  position:relative;
  z-index:9999;
  transition:200ms;
  width: 160px;
}
nav ul li .nav-item:before{
  position:absolute;
  top: -50px;
  right: 0;
  width: 50px;
  height: 50px;
  border-radius: 54% 0 40% 0;
  content:'';
  z-index:-1;
  transition: 300ms;
  transition-timing-function: ease-in-out;
  
}
nav ul li .nav-item.nuxt-link-exact-active:before,nav ul li .nav-item.nuxt-link-exact-active:after{
   box-shadow: 15px 15px 0 0 #000;
   transition: 300ms;

nav ul li .nav-item:after{

  border-radius: 0 0 54% 40%;
  content:'';
  transform:rotate(270deg);
  z-index:-1;
}

<div class="default-layout">
  <nav>
    <ul>
      <li>
        <a class="nav-item nuxt-link-exact-active" onclick="toggle()"
          >Menu 1</a
        >
      </li>
      <li>
        <a class="nav-item" onclick="toggle()">Menu 2</a>
      </li>
      <li>
        <a class="nav-item" onclick="toggle()">Menu 3</a>
      </li>
      <li>
        <a class="nav-item" onclick="toggle()">Menu 4</a>
      </li>
    </ul>
  </nav>
  <main>
    <p>content</p>
  </main>
</div>

您可以根据情况更改宽度大小。
