html5 浮动侧滑菜单栏怎样实现_随笔

一共有4种侧滑动画特效。这款CSS3菜单的特点是鼠标划过时即可以各种动画方式展开和隐藏菜单项，该动画方式由CSS3中的transition-delay属性来完成

使用HTML和CSS制作下拉菜单的方法如下：

1、编写带有div导航的html代码：

2、使用class=“nav”属性的‘div’标签作为菜单的容器。在截图中，在图示的HTML代码中，一个简单的无序列表（ul）来表示主菜单项。

3、在主菜单区域中添加链接。在本步骤中，在无序列表（ul）每一项上添加链接。

4、在“关于我们（About Us）”下方LI标签内添加一个无序列表，它代表其子菜单的链接。

5、制作导航css：

最好是用JS做，但是非要用CSS呢，也可以。如下是我以前写的一个CSS下拉，你可以参考一下：

<html> <head> <title></title> <style>*{margin:0padding:0} ul,li{ list-style-type:none padding:0 margin:0 } #nav li a{ display:block width:100px text-align:center text-decoration:none color:#ffffff background-color:#000000 } #nav li{ position:relative margin-bottom:2pxfloat:leftmargin-right:5px } #nav li ul{ position:absolute left:10px top:20px display:nonewidth:100px } #nav li:hover ul{ display:block } </style> </head> <body><ul id="nav"><li><a href="#">首页</a></li><li><a href="#">关于我们</a><ul><li>我们的故事</li><li>我们的团队</li></ul></li><li><a href="#">我们的服务</a><ul><li>网页设计</li><li>页面制作</li><li>程序开发</li></ul></li><li><a href="#">联系我们</a><ul><li>团队主力</li><li>团队成员</li></ul></li></ul> </body></html>
