Liferay Portal学习笔记之（五）：开发主题风格theme

Liferay Portal为我们提供了非常灵活的主题风格定制功能，自身带了四种风格的theme，在官方网站上提供了很多风格theme的下载，这无疑大大增强了主题风格定制的功能。但是，我们完全可以开发具有自己风格的theme，这里，我们将讨论怎样来开发个性的theme。

第一步：我们将以现有风格classic为模板文件创建新的theme，我们将新theme命名为coldtear
1、将liferay/html/themes目录下的classic文件夹copy一份副本，并修改副本的文件夹名为coldtea
2、在liferay/web-inf目录下新建liferay-look-and-feel-ext.xml文件，文件liferay-look-and-feel.xml是定义主题风格theme的配置文件，为了加以区分，我们在这里新建了该文件的扩展文件liferay-look-and-feel-ext.xml，该文件内容如下：

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">

                portlet-section-selected-bg=#FAFCFE

这里，注意的是修改theme的id和name，以及root-path、templates-path和images-path的路径，这样，我们就可以在主题风格页面看到我们新的theme了。

第二步、分析classic的主题布局的划分
1、打开liferay/html/theme/coldtear/templates目录，该目录下存放着很多jsp文件，打开portal_normal.jsp文件可以看到，该文件是整个页面的主体，通过 <liferay-util:include>标签和<%@ include>方法包含了很多jsp文件，其中top.jsp文件定义了头部信息，navigation.jsp定义了导航菜单，bottom.jsp定义了底部语言标签信息，而页面的主体信息是由 <liferay-theme:box>标签定义的，top="portlet_top.jsp"定义了portlet的标题栏信息，bottom="portlet_bottom.jsp"定义了portlet下面的阴影线，portlet的内容则是由 <liferay-util:include page="&lt;%= Constants.TEXT_HTML_DIR + tilesContent %&gt;">定义的。所有的css样式信息是定义在css_cached.jsp文件中的。
2、liferay portal的页面定义大部分地方都采用了DIV＋CSS的方式，下面将以classic的整个DIV定义框架给出，以说明classic风格的定义方法。
</liferay-util:include> </liferay-theme:box> </liferay-util:include>

<div id="layout-outer-side-decoration">
<div id="layout-inner-side-decoration">
<div id="layout-box">

        <div id="layout-user-menu" style="text-align: right;">
