RAP开发入门-主题更换

通过配置扩展点修改应用主题

ps:需要提前准备好主题（theme.css）文件

<!-- 注册主题扩展点 -->

<extension

point="org.eclipse.rap.ui.themes">

<theme

file="theme/fancy/fancy.css"

id="cn.sunline.lttsweb.application.theme"

name="Default theme">

</theme>

<theme

file="theme/business/business.css"

id="cn.sunline.lttsweb.application.theme.business"

name="Business theme">

</theme>

</extension>

<!-- 绑定主题扩展点 -->

<extension

point="org.eclipse.rap.ui.branding">

<branding

body="body.html"

favicon="icons/16-png.png"

id="cn.sunline.lttsweb.application.branding"

themeId="cn.sunline.lttsweb.application.theme.business"

title="一体化管理平台">

</branding>

</extension>

css定义控件效果语法

Button[PUSH], Button[TOGGLE] {
    border: 2px solid blue;
    color: rgb( 17, 23, 103 );
    background-color: #f9f9f9;
