Liferay Portal爲我們提供了非常靈活的主題風格定製功能，自身帶了四種風格的theme，在官方網站上提供了很多風格theme的下載，這無疑大大增強了主題風格定製的功能。但是，我們完全可以開發具有自己風格的theme，這裏，我們將討論怎樣來開發個性的theme。
第一步：我們將以現有風格classic爲模板文件創建新的theme，我們將新theme命名爲coldtear
1、將liferay/html/themes目錄下的classic文件夾copy一份副本，並修改副本的文件夾名爲coldtea
2、在liferay/web-inf目錄下新建liferay-look-and-feel-ext.xml文件，文件liferay-look-and-feel.xml是定義主題風格theme的配置文件，爲了加以區分，我們在這裏新建了該文件的擴展文件liferay-look-and-feel-ext.xml，該文件內容如下：
![]() <?xml version="1.0"?>
![]() <!DOCTYPE look-and-feel PUBLIC "-//Liferay//DTD Look and Feel 4.0.0//EN" "http://www.liferay.com/dtd/liferay-look-and-feel_4_0_0.dtd">

第二步、分析classic的主題佈局的劃分
1、打開liferay/html/theme/coldtear/templates目錄，該目錄下存放着很多jsp文件，打開portal_normal.jsp文件可以看到，該文件是整個頁面的主體，通過<liferay-util:include />標籤和<%@ include>方法包含了很多jsp文件，其中top.jsp文件定義了頭部信息，navigation.jsp定義了導航菜單，bottom.jsp定義了底部語言標籤信息，而頁面的主體信息是由<liferay-theme:box />標籤定義的，top="portlet_top.jsp"定義了portlet的標題欄信息，bottom="portlet_bottom.jsp"定義了portlet下面的陰影線，portlet的內容則是由<liferay-util:include page="<%= Constants.TEXT_HTML_DIR + tilesContent %>" />定義的。所有的css樣式信息是定義在css_cached.jsp文件中的。
2、liferay portal的頁面定義大部分地方都採用了DIV＋CSS的方式，下面將以classic的整個DIV定義框架給出，以說明classic風格的定義方法。
![]() <div id="layout-outer-side-decoration">
![]() <div id="layout-inner-side-decoration">
![]() <div id="layout-box">
![]() <!-- 定義頭部信息 top.jsp -->
![]() <div id="layout-top-banner">
![]() <div id="layout-user-menu" style="text-align: right;">
![]() <div class="font-small" style="margin-top: 5px;">
![]() <div id="layout-my-places">
![]() <div id="p_p_id_49_" class="portlet-boundary">
![]() <div class="portlet-borderless-container">
![]() </div>
![]() </div>
![]() </div>
![]() </div>
![]() </div>
![]() </div>
![]() <!-- 定義導航菜單 navigation.jsp -->
![]() <div id="layout-nav-container">
![]() <div class="layout-nav-tabs-box">
![]() <div class="layout-tab"></div>
![]() <div class="layout-tab"></div>
![]() <div class="layout-tab-selected"></div>
![]() <div class="layout-tab"></div>
![]() </div>
![]() <div id="layout-global-search"></div>
![]() </div>
![]() <div class="portlet-bottom-decoration-2"><div><div></div></div></div>
![]() <!-- 定義主體portlet信息部分 -->
![]() <div id="layout-content-outer-decoration">
![]() <div id="layout-content-inner-decoration">
![]() <div id="layout-content-container">
![]() <div id="layout-column_column-1">
![]() <div id="p_p_id_73_INSTANCE_9Q28_" class="portlet-boundary">
![]() <div class="portlet-container">
![]() <!-- 定義portlet標題欄信息 portlet-top.jsp -->
![]() <div class="portlet-header-bar" id="portlet-header-bar_73_INSTANCE_9Q28" onmouseover="PortletHeaderBar.show(this.id)" onmouseout="PortletHeaderBar.hide(this.id)">
![]() <div class="portlet-wrap-title">
![]() </div>
![]() <div class="portlet-small-icon-bar" style="display: none;">
![]() </div>
![]() </div>
![]() <!--&nb |
