如何在全角菜单中更改幻灯片的过渡

Question

我有一个基本的全屏滑入式菜单。它从左上角向外扩展以适应全屏。但是，我不希望它向外扩展。相反，我希望它从左侧滑入只是​​为了占据全屏。这可能吗？

<div class="top">
    <!-- place brand icon here -->
</div>

<div class="menu-collapsed">
  <div class="bar"></div>
       <nav>
  <ul>
    <li><a href="#">Home</a></li>
    <li><a href="#">About</a></li>
    <li><a href="#">Clients</a></li>
    <li><a href="#">Contact Us</a></li>
    <li><a href="#">Clients</a></li>
    <li><a href="#">Contact Us</a></li>
  </ul>
</nav>  
</div>

我已将它放在 codepen 上（由于某种原因，它在这里根本不起作用）http://codepen.io/anon/pen/Ywypby 但我认为这是因为 Codepen 不会运行脚本。

Answer 1

您的动画在 codepen 中不起作用的原因是您没有在 JS 部分中加载 JQuery。只需单击小设置图标并将其加载到项目中。

要让您的动画从左侧滑入，您只需将过渡定位在 .menu-collapsed 和 .menu-expanded....

而不是

transition: all XXs;

做

transition: width XXs;

XX 正是你过渡的时候。
