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"?>


<!--</span-->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">




<look-and-feel>

        <version>4.0.0<!--</span-->version>


    <!--</span-->compatibility>


    <company-limit>


        <company-includes />


        <company-excludes />

                portlet-section-alternate=#000000


                portlet-section-alternate-bg=#CFD7FB




                portlet-section-alternate-hover=#FFFFFF


                portlet-section-alternate-hover-bg=#AC6CFA




                portlet-section-selected=#7AA0EC


                portlet-section-selected-bg=#FAFCFE




                portlet-section-selected-hover=#00329A


                portlet-section-selected-hover-bg=#C0D2F7

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 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
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 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。


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


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


<div id="layout-box">


    <!--</span><span style="COLOR: #000000"> 定义头部信息 top.jsp </span><span style="COLOR: #000000">-->


    <div id="layout-top-banner">
