纯css3开发的响应式设计动画菜单（支持ie8）

这是一个响应式设计的菜单。单击列表图标，当你显示屏大小可以完全水平放下所有菜单项时，菜单水平显示（如图1）。当你的显示屏不能水平放置所有菜单项时，菜单垂直显示（如图2）。 而且显示的时候是以动画的型式显示。效果相当的好。

下面贴出实现这功能的源代码，这是一个纯用css3实现的菜单

html代码：

 <div class="container">
        <!--[if lte IE 8]>
<style>

        .iconicmenu > label{
        border-width: 7px;
        background: #eee;
        }

        .iconicmenu:hover ul{
            left: 8px; /* show menu onmouseover in IE8 and below */
        }

</style>
<![endif]-->
        <div class="iconicmenu">
            <input type="checkbox" id="togglebox" />
            <ul>
                <li><a targe="_blank" href="http://www.w2bc.com/Shili/css3%E8%8F%9C%E5%8D%95">Home</a></li>

                <li>
                    <label for="togglebox">
                    </label>
                </li>
            </ul>
            <label class="toggler" for="togglebox">
                Menu</label>
        </div>
    </div>

这里加入了兼容ie8的hack 。
