如何使用幻灯片动画移动div？

Question

我正在使用html，css和javascript使边栏更加直观。 我想用慢动画（如幻灯片）移动html代码中的侧边栏。 现在，我只使用纯JavaScript。但是，如果可行，可以使用jquery解决此问题。 但是现在，它像演示一样移动。现在移动不平稳。 我该怎么解决？

// Function for the button that open the sidebar.

  //Function for the button for close the sidebar.

这是使用CSS动画的非常简单的演示。请注意，这不是生产代码，只是滑动动画的一个肮脏的例子。

jsfiddle： https://jsfiddle.net/CriticalError/4qru8mb6/

HTML

<div id="action-menu">
Click to Open Menu
</div>
<div id="sub-menu">
  <a href="#">My Link 1</a>
  <br />
  <a href="#">My Link 2</a>
  <br />
  <a href="#">My Link 3</a>
</div>

CSS

body {
  padding: 0;
  margin: 0;
}
#action-menu {
  position: relative;
  width: 100%;
  padding: 10px 4px 10px 4px;
  background-color: silver;
  cursor: pointer;
}
#sub-menu {
  position: relative;
  padding-left: 10px;
  overflow: hidden;
  height: 0px;
  background-color: red;
}
.slideOpen {
  animation: slideOpen 1s forwards;
}
.slideShut{
  animation: slideShut 1s forwards;
}
@keyframes slideOpen {
  0% { height: 0px; }
  100% { height: 100px; }
}
@keyframes slideShut {
  0% { height: 100px; }
  100% { height: 0px; }
}

JavaScript

var actionMenu = document.getElementById( "action-menu" );
var isOpen = false;

actionMenu.addEventListener( "click", function () {

    if ( isOpen ) {

    document.getElementById( "sub-menu" ).className = "slideShut";
    isOpen = false;

  }
  else {

    document.getElementById( "sub-menu" ).className = "slideOpen";
    isOpen = true;

  }

})

检查我的示例笔

Simple Navigation Animation 我在导航容器上切换了一个触发CSS转换的类。相当容易使用

https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions

您还可以使用@keyframes，这也需要进行类切换
