這是一個完全用CSS實現的中英文雙語導覽功能表，無指令碼和圖片，初始時，菜單語言是英文，當滑鼠移至上方在菜單上時，其變成中文，當然你也可以反過來做。
<ul id="nav">
<li><a class="bi" href="index.html">Home<span>首 頁</span></a></li>
</ul>
從上面代碼可以看出，中文放在 span 標籤裡，關鍵是需要在初始時，使其的屬性不可見。
.bi{
position: relative;
z-index: 0;
}
.bi:hover{
z-index: 99;
}
.bi:hover span{
visibility: visible;
top: 0;
left: 0;
cursor: pointer;
}
.bi span{
position: absolute;
left: -999em;
visibility: hidden;
}
#nav li a,.bi:hover span{
line-height: 20px;
text-decoration: none;
background: #DDDDDD;
color: #666666;
display: block;
width: 80px;
text-align: center;
}
#nav li a:hover,.bi:hover span{
color: #FFFFFF;
background: #DC4E1B;
}
.bi:hover span{
padding-top: 2px;
}
連結的屬性是相對定位，那在此標籤裡的元素可將其作為參照點。 在 span 元素裡的中文因其設定了不可見，所以在初始狀態時，只能顯示英文。而當滑鼠移至上方在菜單上時，
span 元素裡的設定變為可見，Z軸為99 ，覆蓋在英文上面，從而實現了語言文字的轉換。缺點：因為中英文字的長度關係，不能實現自適應寬度，只能固定寬度。
