我的例子是：http://www.interfaithmedical.com/sfish/example.htmlUL問題的寬度，CSS寬度不工作
它包含HTML標籤：
<ul class="sf-menu">
我想舒展UL的確切960像素的寬度。每個LI均勻拉伸並且能夠將其放入DIV中而不需要任何填充。我試圖增加主要UL的寬度：
.sf-menu ul {
position: absolute;
top: -999em;
width: 960px;
}
但它的寬度未設置爲960px。寬度：屬性似乎是無效的。

對於用戶界面全寬刪除浮動：從.sf菜單 – supersaiyan
左邊的CSS文件中間我刪除浮動：左，但沒有改變寬度。 – Interfaith
