停止时折叠动画：悬停

Question

我有很多麻烦试图这样做。当我将其中一个元素悬停时，我终于找到了如何为一个旁边的菜单做扩展动画。

问题是我想做一个动画来关闭它。我尝试将动画制作为开放动画（使用from - ＆gt; to）并且它不起作用。

我尝试使用列表中的不同容器（ul，div，li，无论一个一个）进行最大高度的转换，我尝试搜索不同类型的已经制作的动画，但没有一个工作，菜单刚刚弹出没有动画就消失了。

我基本上想要的是一个平滑的动画来向下移动（到达）其他元素，然后在菜单关闭时向上移动。

实际上它有2个动画：扩展最大高度，并从右向左移动。但我无法通过动画来关闭它。

我不想使用Javascript，因为它适用于学校项目，但我们还没有看到它。

Answer 1

您可以使用转换而不是动画。我的演示：

 aside {
  width: 25%;
  display: inline-block;
  vertical-align: top;
  margin-top: 20px;
  margin-bottom: 20px;
}

aside > div:not(#marcador) {
  background-color: rgb(40, 44, 47);
  border-radius: 15px;
  box-shadow: 0 2px 2px -1px rgba(0, 0, 0, 0.055);
  color: silver;
  display: block;
  margin-top: 5px;
  margin-right: -15px;
  font-family: "Press Start 2P";
  font-size: 0.7em;
  line-height: 10px;
  padding: 15px;
  -moz-transition: opacity 0.4s ease-in-out;
  -o-transition: opacity 0.4s ease-in-out;
  -webkit-transition: opacity 0.4s ease-in-out;
  transition: opacity 0.4s ease-in-out;
}

#marcador li> div {
  opacity: 0;
  margin-left: 300px;
  -webkit-transition: all 0.5s;
  transition: all 0.5s;
}

#marcador li:hover > div {
  opacity: 1;
  padding-left: 20px;
  margin-left: 0;
}

#marcador li> div >ul >li {
  max-height: 0;
  transition: all 0.5s;
}
#marcador li:hover> div >ul >li {
  max-height: 40px;
}

#marcador li:hover{
  max-height: 500px !important;
}

#marcador li:hover > a {
  display: block;
  opacity: 1;
  visibility: visible;
}

#marcador ul {
  margin: 0;
  padding: 0;
  list-style-type: none;
  position: static;
}

#marcador ul li > a {
  background-color: rgb(40, 44, 47);
  border-radius: 15px;
  box-shadow: 0 2px 2px -1px rgba(0, 0, 0, 0.055);
  color: silver;
  display: block;
  margin-right: -15px;
  font-family: "Press Start 2P";
  font-size: 0.7em;
  line-height: 10px;
  padding: 15px;
  padding-left: 35px;
}

#marcador ul ul {
  padding: 0;
  margin: auto;
}

#marcador ul ul a {
  margin-left: 20px;
  background-color: dimgray;
}

#marcador ul ul ul a {
  margin-left: 40px;
  background-color: gray;
  color: black;
}

#marcador img {
  float: left;
  vertical-align: middle;
  display: inline-block;
  opacity: 0;
  position: absolute;
  visibility: hidden;
  margin-left: -20px;
}

#marcador li:hover > a > img {
  opacity: 1;
  visibility: visible;
}

#marcador a:hover {
  color: orange;
}
