       <a href="#"> Web Dev</a> 
       <a href="#"> Web Design</a> 
       <a href="#"> Map</a> 
    </div>

---------------------------箭头菜单---------------------------

#menu a, #menu a:visited {text-decoration:none; text-align:center;color:#c00; display:block;padding:4px;
    background-color:#fff; border:solid 1px #fff;position:relative;width:130px;}

       <a href="#"><span class="left"></span>Map<span class="right"></span></a>
    </div>

---------------------------带说明信息的菜单---------------------------

直接在上个案例中，css里增加一段新的样式。html中新增一个类名为intro的span标签即可。

#menu a:hover span.intro{font-size:12px;display:block;position:absolute;left:150px;top:0;padding:5px;width:100px;height:auto;background-color:#eee;color:#000;border:1px dashed #234}

<a href="#"><span class="left"></span> Home<span class="right"></span><span class="intro">这里说明Home菜单项</span></a>

 ---------------------------斜角水平菜单---------------------------

#menu {font-family:Arial;font-size:14px;}
#menu a,#menu a:visited{display:block;float:left;position:relative;background-color:#c00;color:#fff;text-decoration:none;padding:6px;margin:1px 0 0 1px}
#menu a span{height:0;width:0;border-bottom:solid 6px #c00;border-left:solid 6px #fff;position:absolute;top:0;left:0;overflow:hidden}
#menu a span{height:0;width:0;border-bottom:solid 6px #c00;border-left:solid 6px #fff;position:absolute;top:0;left:0;overflow:hidden}#menu a:hover{background-color:#F90;color:#333}
