DIV CSS列形導航一例，超酷解析

　　如圖效果:

　　先看看XHTML代碼：

        <div id="navcontainer"> <p><ul id="navlist"> </p><p><li id="active"><a href="http://./" id="current">Item one</a> </p><p><ul id="subnavlist"> </p><p><li id="subactive"><a href="http://./" id="subcurrent">Subitem one</a></li> </p><p><li><a href="http://./">Subitem two</a></li> </p><p><li><a href="http://./">Subitem three</a></li> </p><p><li><a href="http://./">Subitem four</a></li> </p><p></ul> </p><p></li> </p><p><li><a href="http://./">Item two</a></li> </p><p><li><a href="http://./">Item three</a></li> </p><p><li><a href="http://./">Item four</a></li> </p><p></ul> </p></div>

　　看看CSS是如何定久相關元素的：

       #navcontainer { margin-left: 30px; } <p>#navcontainer ul </p><p>{ </p><p>margin: 0; </p><p>padding: 0; </p><p>list-style-type: none; </p><p>font-family: verdana, arial, Helvetica, sans-serif; </p><p>} </p><p>#navcontainer li { margin: 0; } </p><p>#navcontainer a </p><p>{ </p><p>display: block; </p><p>padding: 5px 10px; </p><p>width: 140px; </p><p>color: #000; </p><p>background-color: #ADC1AD; </p><p>text-decoration: none; </p><p>border-top: 1px solid #fff; </p><p>border-left: 1px solid #fff; </p><p>border-bottom: 1px solid #333; </p><p>border-right: 1px solid #333; </p><p>font-weight: bold; </p><p>font-size: .8em; </p><p>background-image: url(images/vertical06.jpg); </p><p>background-repeat: no-repeat; </p><p>background-position: 0 0; </p><p>} </p><p>#navcontainer a:hover </p><p>{ </p><p>color: #000; </p><p>background-color: #889E88; </p><p>text-decoration: none; </p><p>border-top: 1px solid #333; </p><p>border-left: 1px solid #333; </p><p>border-bottom: 1px solid #fff; </p><p>border-right: 1px solid #fff; </p><p>background-image: url(images/vertical06a.jpg); </p><p>background-repeat: no-repeat; </p><p>background-position: 0 0; </p><p>} </p><p>#navcontainer ul ul li { margin: 0; } </p><p>#navcontainer ul ul a </p><p>{ </p><p>display: block; </p><p>padding: 5px 5px 5px 30px; </p><p>width: 125px; </p><p>color: #000; </p><p>background-color: #C5D8C5; </p><p>text-decoration: none; </p><p>font-weight: normal; </p><p>} </p><p>#navcontainer ul ul a:hover </p><p>{ </p><p>color: #000; </p><p>background-color: #889E88; </p><p>text-decoration: none; </p>}
