我对我的 asp.net 页面进行样式设置有一点问题：
在我的 aspx 页面顶部，我声明：
<head>
<meta charset="utf-8">
<title>CSS3 Menu - Impressionist UI - by Valeriu Timbuc for Design Modo</title>
<link rel="stylesheet" href="css/style.css" media="screen">
<style type="text/css">
html, body { margin: 0; padding: 0; }
body { margin: 5px; background: #f2f2f2 no-repeat top center; }
ul.menu { margin: 5px auto 0 auto; }
</style>
<meta name="robots" content="noindex,follow" />
</head>
在某些地方我有这个代码：
<div class="rounded-corners"; style=" margin-left:50px; margin-right:50px; ">
<asp:GridView id="MyGridView"
DataSourceID="MyDataSource1"
AutoGenerateColumns="False"
GridLines="Both"
AllowSorting="True"
AllowPaging="True"
CssClass="mGrid"
PagerStyle-CssClass="pgr"
AlternatingRowStyle-CssClass="alt"
Runat="Server" PageSize="35">
<columns>
<asp:boundfield datafield="FICHIER"
readonly="true"
headertext="Fichier"
ItemStyle-CssClass="CellFile">
</asp:boundfield>
在后者中，我尝试使用ItemStyle-CssClass="CellFile"in irder 来定义 padding-left 和颜色。所以在我的css文件中我有：
/* Reset */

.menu ul,
.menu li,
.menu a {

}
.CellFile
{
padding-left:100px;
color:Aqua;
}
因此，当我运行该样式时，该样式将不适用，但是当我删除该<head></head>部分时，该样式可以正常工作。我是 css 和 asp.net 的新手，我猜这个问题在样式声明中的某个地方。我怎样才能让它工作？
谢谢你。
