　　要使用VBox布局方式，首先的熟悉下一下几个主要属性：
　　一、align：字符类型，指示组件在容器内的对齐方式。有如下几种属性。
　　1、left（默认）：排列于容器左侧。
　　2、center ：控件在容器水平居中。
　　3、stretch：控件横向拉伸至容器大小
　　4、stretchmax:控件横向拉伸，宽度为最宽控件的宽。
　　二、flex:数字类型，指示组件在容器中水平呈现方式，通俗的讲，就是指示组件在容器中的相对宽度。
　　三、pack : 字符类型，指示组件在容器的位置，有如下几种属性。
　　1、start（默认）：组件在容器上边
　　2、center：组件在容器中间
　　3、end：组件在容器的下边
　　
　　HTML代码：

VBox---MHZG.NET
html, body {
font: normal 12px verdana;
margin: 0;
padding: 0;
border: 0 none;
}

VBox---MHZG.NET

html, body {
font: normal 12px verdana;
margin: 0;
padding: 0;
border: 0 none;
}

　　vbox.js：
