使用纯 CSS 制作动画下拉菜单就像 Bootstrap 一样

Question

我正在使用自己的项目构建样式表 (CSS)，就像 bootstrap 所做的那样。但是，我尝试只使用 PURE CSS - no javascript or jquery even flash to do那。

现在，我在调整小尺寸时遇到动画下拉菜单问题就像手机版的样子。

我想要的是：

First, When the browser resize less then 768 and 480 or (55%), the animated circle menu appears, animating and Menu is hidden. After that, on hover (<div class="acn-menu"></div>), the animated circle menu runs again. When user click or touch the animated circle menu, the animated circle menu stops and the dropdown menu appears and push the content below it with no scrollbar at the same time as the animated circle rolls back and stops.

Second, How to be compatible with all browsers (even, in IE).

这是我一个多星期以来所做的：（抱歉我的英语不好）：我刚刚在下面的这个网站上传了示例：

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>

                    </li>
                    <li><a class="dropdown" href="#">Pembayaran <span 
class="fa fa-caret-down"></span> </a>
                        <ul class="sub-menu">
                            <li><a href="#">Via Transfer Bank</a></li>

任何帮助都会很棒！

Answer 1

没有必要不使用 javascript 因为大多数人总是启用它，而且它有很棒的功能。

上面说了我在这里找到了一个如何帮助你的例子：link

在那里你可以找到两个选项，目标伪选择器和一个 CSS3 选择器技巧。

希望对你有帮助:3

动画菜单

When the browser resize less then 768 and 480 or (55%), the animated circle menu appears

这是我在 css 中使用媒体查询完成的：@media screen and (max-width:768px) 并设置 animation:

After that, on hover (), the animated circle menu runs again.

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

When user click or touch the animated circle menu, the animated circle menu stops and the dropdown menu appears and push the content below it with no scrollbar at the same time as the animated circle rolls back and stops.

点击是通过 input type="checkbox" 元素完成的。这是一个特殊的 css 伪选择器 :checked。这让我们可以更改 :checked 的样式。我们所做的是将它与兄弟选择器结合起来 #input:checked ~ .sibling。现在我们可以在单击复选框时设置 .sibling 样式。除此之外，还为复选框添加了标签。 label for="#ID" 并使用 display:none;

隐藏实际的复选框

用 transform: rotate(180deg); 完成回滚圆圈。

浏览器支持应该没问题，但是我还没有为所有的转换和动画添加所有的前缀。

过渡和动画 CSS3 所以 IE9 不支持。
应该在 IE10 及更高版本中工作。（可能缺少 -ms- 前缀）
在 Chrome 40.0.
