母版页制作其实应该算是一个比较基础的工作，但是熟练制作出灵活、完整的母版页的人却很少。。为什么会这样呢，分析原因有几个，主要的问题应该是母版页制作是介于开发和美工之间的工作，开发人员关注代码，美工关注界面效果，就忽略和回避了这部分，都不愿意作怎么办，那就我来作吧。。

首先MOSS的母版页也是来自于asp.net的母版页，原理都是一样的。

基于微软提供的文档，母版页制作有两种方式：一，布局变化不大的情况下，在原母版页上修改；二，重新制作。

我们主要说说重新制作吧。。

最简单的理解就是：

第一，先知道哪些是母板页中必须有的元素；

第二，从美工处拿到界面的展示效果和html布局，css样式表；

第三，从SPD创建一个新的母版页，将html代码复制进去；

第四，将css放到相应位置，母版页应用对应的css；

第五，将美工模拟的控件用母版页中的占位符替换；

第六，除了必须的元素外，还需要添加什么附加控件，也加到相应的位置；

完成！

下面详细说下每一步：

一、哪些是母板页中必须有的元素

空白的，没有样式的包括所有占位符的母版页：

<%-- Identifies this page as a .master page written in C# and registers tag prefixes, namespaces, assemblies, and controls. --%>
<%@ Master language="C#" %>

<%-- Uses the Microsoft Office namespace and schema. --%>
<html>
<WebPartPages:SPWebPartManager runat="server"/>
<SharePoint:RobotsMetaTag runat="server"/>
<head runat="server">
    <asp:ContentPlaceHolder runat="server" id="head">
      <title>
        <asp:ContentPlaceHolder id="PlaceHolderPageTitle" runat="server" />
      </title>
    </asp:ContentPlaceHolder>
    <Sharepoint:CssLink runat="server"/>
    <asp:ContentPlaceHolder id="PlaceHolderAdditionalPageHead" runat="server" />
</head>
<body onload="javascript:_spBodyOnLoadWrapper();">
    <form runat="server" onsubmit="return _spFormOnSubmitWrapper();">
      <wssuc:Welcome id="explitLogout" runat="server"/>
      <PublishingSiteAction:SiteActionMenu runat="server"/>
      <PublishingWebControls:AuthoringContainer id="authoringcontrols" runat="server">
        <PublishingConsole:Console runat="server" />
      </PublishingWebControls:AuthoringContainer>
      <asp:ContentPlaceHolder id="PlaceHolderMain" runat="server" />
        <asp:Panel visible="false" runat="server">
<asp:ContentPlaceHolder id="PlaceHolderSearchArea" runat="server"/>
<asp:ContentPlaceHolder id="PlaceHolderTitleBreadcrumb" runat="server"/>
<asp:ContentPlaceHolder id="PlaceHolderPageTitleInTitleArea" runat="server"/>
<asp:ContentPlaceHolder id="PlaceHolderLeftNavBar" runat="server"/>
<asp:ContentPlaceHolder ID="PlaceHolderPageImage" runat="server"/>
<asp:ContentPlaceHolder ID="PlaceHolderBodyLeftBorder" runat="server"/>
<asp:ContentPlaceHolder ID="PlaceHolderNavSpacer" runat="server"/>
<asp:ContentPlaceHolder ID="PlaceHolderTitleLeftBorder" runat="server"/>
<asp:ContentPlaceHolder ID="PlaceHolderTitleAreaSeparator" runat="server"/>
<asp:ContentPlaceHolder ID="PlaceHolderMiniConsole" runat="server"/>
<asp:ContentPlaceHolder id="PlaceHolderCalendarNavigator" runat ="server" />
<asp:ContentPlaceHolder id="PlaceHolderLeftActions" runat ="server"/>
<asp:ContentPlaceHolder id="PlaceHolderPageDescription" runat ="server"/>
<asp:ContentPlaceHolder id="PlaceHolderBodyAreaClass" runat ="server"/>
<asp:ContentPlaceHolder id="PlaceHolderTitleAreaClass" runat ="server"/>
</asp:Panel>
    </form>
</body>
</html>

然后我们来分别认识下这些占位符：

1、<asp:ContentPlaceHolder ID="PlaceHolderGlobalNavigationSiteMap" runat="server" />
就是一般放在最上面一行显示站点名称的，点击返回到首页；这是占位符，包含控件默认的写法是：

<asp:ContentPlaceHolder id="PlaceHolderGlobalNavigationSiteMap" runat="server">
<asp:SiteMapPath SiteMapProvider="SPSiteMapProvider" id="GlobalNavigationSiteMap" RenderCurrentNodeAsLink="true" SkipLinkText="" NodeStyle-CssClass="ms-sitemapdirectional" runat="server"/>
</asp:ContentPlaceHolder>
2、<asp:ContentPlaceHolder ID="PlaceHolderGlobalNavigation" runat="server" />
放置顶部一行内容的占位符；一般中间可以加上表格，并放上需要的东西，例如欢迎信息，我的站点等。例如欢迎信息：

<asp:ContentPlaceHolder ID="PlaceHolderGlobalNavigation" runat="server">
<wssuc:Welcome id="IdWelcome" runat="server" EnableViewState="false"></wssuc:Welcome> </asp:ContentPlaceHolder>
欢迎信息也可以单独拿出来放在其他位置。

3、<asp:ContentPlaceHolder ID="PlaceHolderSiteName" runat="server" />
放置LOGO旁边的大的站点名称的占位符；中间加了内容的默认写法是：

<SharePoint:SPLinkButton runat="server" NavigateUrl="~site/" id="onetidProjectPropertyTitle">
<SharePoint:ProjectProperty Property="Title" runat="server" />
</SharePoint:SPLinkButton>
