javascript - 在移动设备上查看时如何将导航项移出屏幕

Question

我正在学习如何为移动设备构建汉堡菜单。

我构建了一个包含三个子项的导航。 Logo 、导航项和汉堡菜单。我使用 flexbox 将它们并排放置并在桌面上的汉堡菜单上显示:无以最初隐藏它。

我试过使用相对位置/绝对位置，但效果不佳。此外，将 flex-direction: row 更改为 column 也无济于事。

这是导航栏的标记

<nav class="nav">
  <div class="brand"><h4>The Brand</h4></div>

  <div class="navigation">
    <ul class="navigation__list">
      <li class="navigation__item">
        <a href="#">Home</a>
      </li>
      <li class="navigation__item">
        <a href="#">About</a>
      </li>
      <li class="navigation__item">
        <a href="#">Services</a>
      </li>
      <li class="navigation__item">
        <a href="#">Gallery</a>
      </li>
      <li class="navigation__item">
        <a href="#">Blog</a>
      </li>
      <li class="navigation__item">
        <a href="#">Contact</a>
      </li>
    </ul>
  </div>

  <button class="hamburger">
    <span class="hamburger__box">
      <span class="hamburger__inner"></span>
    </span>
  </button>
</nav>

我想要实现的是:在移动设备上，汉堡包菜单应该出现。导航元素应该从屏幕上消失，并且应该垂直放置。我希望它们在单击汉堡包时从右侧滑入。
