September 18th, 2009 发表评论 阅读评论

这款下拉菜单栏的实现非常简单,没有用到复杂的JS代码,完全依靠css代码来实现的,只需进行简单的修改变换就可以了,以下是代码实例:

html代码:

<div id="nav">
    <ul>
    <li class="menu2" onMouseOver="this.className='menu1'" onMouseOut="this.className='menu2'">Home Page    
    <div class="list">
        <a href="http://www.wer.pp.ru/">云在天边</a><br />
        <a href="#">我的首页</a><br />
        <a href="#">我的日志</a><br />
        <a href="#">我的日志</a><br />
        <a href="#">我的相册</a><br />
        <a href="#">我的收藏</a><br />
    </div>
    </li>
    <li class="menu2" onMouseOver="this.className='menu1'" onMouseOut="this.className='menu2'">Connection 
    <div class="list">
        <a href="http://www.wer.pp.ru/">云在天边</a><br />
        <a href="#">我的首页</a><br />
        <a href="#">我的日志</a><br />
        <a href="#">我的相册</a><br />
        <a href="#">我的收藏</a><br />
    </div>
    </li>
    <li class="menu2" onMouseOver="this.className='menu1'" onMouseOut="this.className='menu2'">My Files    
    <div class="list">
        <a href="http://www.wer.pp.ru/">云在天边</a><br />
        <a href="#">我的相册</a><br />
        <a href="#">我的收藏</a><br />
    </div>
    </li>
    <li class="menu2" onMouseOver="this.className='menu1'" onMouseOut="this.className='menu2'">Management    
    <div class="list">
        <a href="http://www.wer.pp.ru/">云在天边</a><br />
        <a href="#">我的首页</a><br />
        <a href="#">我的日志</a><br />
        <a href="#">我的相册</a><br />
        <a href="#">我的收藏</a><br />
        <a href="#">我的日志</a><br />
        <a href="#">我的相册</a><br />
        <a href="#">我的收藏</a><br />
    </div>
    </li>
    </ul>
</div>
