转换不起作用
Transition doesnt work
我有一个关于转换的问题，我正在尝试使用转换创建一个自定义的可折叠侧边栏。这意味着，一旦图像悬停在上面，#nav就会出现。但不知怎么的，这不起作用，请帮忙。

这是有效的，我还将#nav{ top:0; }更改为#nav{ top:27px; }，以避免当#nav部分展开时，它将覆盖#menu切换，并且"悬停"效果无法制作古怪的动画。
同时将此选择器#menu:hover ~ #nav更改为#menu:hover ~ #nav, #nav:hover，以便当您将从#menu悬停到#nav部分时，#nav部分将保持展开状态，并且不会转换回其原始宽度。
JS Fiddle-更新
CSS:
#nav {
/* code */
top: 27px;
/* code */
}
#menu:hover ~ #nav, #nav:hover{
width: 50%;
}
