用纯CSS制作动画下拉菜单，就像Bootstrap一样

Question

用纯CSS制作动画下拉菜单，就像Bootstrap一样

4

我正在开发一个项目，构建一个像bootstrap一样的样式表（CSS）。然而，我尝试只使用PURE CSS - 没有JavaScript或jQuery甚至Flash来完成这个项目。

目前，我在 Animated Menu Dropdown 组件的小尺寸展现有困难，就像移动端看起来那样。

我的要求是：

首先，当浏览器大小小于768和480或(55%)时，动画圆形菜单出现，Menu 被隐藏。之后，在悬停时(<div class="acn-menu"></div>)，动画圆形菜单再次运行。当用户点击或触摸动画圆形菜单时，动画圆形菜单停止，并且下拉菜单出现并将内容推到其下面，同时动画圆形回滚并停止，不出现滚动条。

其次，如何与所有浏览器兼容(包括IE)。

以下是我一个多星期所做的: (对不起，我的英语不好):

我刚刚上传了以下网站中的示例：

演示 The Dropdown-Menu

HTML：

<header>
<div id="acn-border"></div><div class="acn-title"><a href="#">
<h1>Appacyber</h1></a></div>
    <div class="menu-container">
        <div class="acn-menu"></div>
            <nav>
                <ul class="main-menu">
                    <li><a href="#" class="home"><span class="fa 
fa-home"></span> Home</a></li>
                    <li><a href="#">Produk <span class="fa fa-caret-
down"></span> </a>
                        <ul class="sub-menu">
                            <li><a href="#">Desain Website</a></li>
                            <li><a href="#">Desain/Edit CMS</a></li>

我看到它弄乱了我的代码... :p - 悬停效果可以，但当我添加一行文本时，它不能将下面的内容向下推。 - Joe Kdw

并不需要因为大多数人都启用了它并且它具有强大的功能而不使用JavaScript。

说到上面的话，我在这里找到了一个帮助你的例子：link。

在那里，你可以找到两个选项，目标伪选择器和CSS3选择器技巧。

希望它能帮到你 :3

动画菜单

当浏览器的大小小于768和480或（55％）时，动画圆形菜单出现。

这是通过CSS中的媒体查询完成的：@media screen and (max-width:768px) 并设置了一个 animation:

之后，悬停时，动画圆形菜单再次运行。

这是通过 :hover 语句中的 transform: rotate(180deg); 完成的。

当用户单击或触摸动画圆形菜单时，动画圆形菜单停止并显示下拉菜单，并将其下面的内容推开，同时动画圆形菜单滚回并停止。

点击是使用 input type="checkbox" 元素完成的。这是用于特殊的CSS伪选择器:checked。这让我们可以更改:checked的样式。我们所做的是将其与相邻选择器结合起来，因此 #input:checked ~ .sibling。现在，我们可以在单击复选框时为 .sibling 设置样式。除此之外，还添加了复选框的标签。label for="#ID" 并用 display:none; 隐藏了实际的复选框。

滚动圆形是通过使用 transform: rotate(180deg); 完成的。

浏览器支持应该没问题，但我没有为所有转换和动画添加所有前缀。

CSS3的过渡和动画不支持IE9。
应该可以在IE10及以上版本中正常工作。（可能缺少-ms-前缀）
在Chrome 40.0 中测试过。
