只需添加一个CSS ContentPlaceHolder，默认值即可。
Just add a CSS ContentPlaceHolder with a default value in it.
基本上，将包含您指定为默认值的CSS文件，除非您用子页面中的标记覆盖该占位符。
Basically, the CSS file you specify as default will be included unless you override that placeholder with an tag from a child page.
<head>
<asp:ContentPlaceHolder ID="Stylesheets" runat="server">
<link rel="stylesheet" href="/css/master.css" type="text/css" />
</asp:ContentPlaceHolder>
</head>
然后从使用该母版页的任何页面中，您都可以使用其他样式表简单地覆盖它。
Then from any pages using that Master Page, you can simply override that with a different stylesheet.

<asp:Content ID="Content1" ContentPlaceHolderID="Stylesheets" runat="server">
<link rel="stylesheet" href="/css/Style.css" type="text/css" />
