當你配置一個MOSS站點時，第一步中通常會建立一個或多個母版頁。使用母版頁可以包含很多MOSS站點中的元素，例如導航欄、搜索文本框、登陸控件等等，也包含了對定義站點統一樣式的CSS文件。MOSS的站點和站點中所有的頁面都是通過母版頁來實現統一的用戶體現和風格。根據你的需要，也可以對站點集中不同的站點使用不同的母版頁來區分每個站點所處於門戶中的區域。
當你在MOSS中定義一個站點級時，系統會自動地創建一個母版頁庫包含了所有的母版頁和站點集的頁面布局。如果這個站點集用到了發布門戶或是協作門戶模板，則母版頁庫中會包含幾個不同的母版頁，你可以選擇使用不同的母版頁使站點看起來更加個性化。
在MOSS頁面定制中建立母版頁是最重要的第一步，它將花費很多時間才能完成。本文將講述如何建立一個滿足MOSS要求的最精簡功能的母版頁，後面的代碼會提供一個僅能保證MOSS頁面控件正常布局的母版頁。
你可以隨便的建立一個空的母版頁，但是我們不推薦這樣做，因為一個完全空白的母版頁中並不包含能使MOSS頁面模型正常工作的Content PlaceHolder。而下面的示例代碼中會包含所有必須的Content PlaceHolder。
你可以使用記事本，類似於Sharepoint 2007 Designer的Web編輯器，類似於VS 2005的IDE來編輯母版頁，本文使用的是Sharepoint 2007 Designer 。
MOSS 要求一個母版頁必須包含標題、圖標、登陸、搜索等區域和一些基礎結構元素包括頁面區域、分格欄、邊框、控制台和描述文字PlaceHolder。
MOSS提供的母版頁需要基於WSS的SPWeb類下的SPWeb.CustomMasterUrl。
建立一個最精簡的母版頁步驟如下。
step(1): 打開Sharepoint Designer.
step(2): 在文件菜單點擊New，選擇Sharepiont Content，選擇Page 標簽。
step(3): 雙擊母版頁來創建一個母版頁。
step(4): 選擇在設計模式下查看母版頁，母版頁覆蓋了頭部和左邊的一些區域，幾個content placeholders是可見的。
step(5): 選擇在代碼模式下查看母版頁。
step(6): 把下面的代碼拷貝並粘貼到母板頁中。
