本文介绍如何禁用默认模板并创建纯HTML页面的方法，通过具体实例展示了如何设置页面的完整结构，包括DOCTYPE、html、head及body标签，并利用CSS样式实现特定效果。

render layout: false


不使用默认模板 就是由header footer lefter righter组成的完整的html， 生成一个原生态的html没有之前所有的header头等一些其他的东西， 生成的页面是单独的页面得自己给HTML加头即：

<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
</head>

<body>
The content of the document......
</body>

</html>

实例:

<!DOCTYPE html>
<html style="height: 100%; width: 100%">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1, maximum-scale=1, user-scalable=no" />
<title>欧洲杯</title>
</head>
<body style="margin:0; height: 100%; width: 100%" align="center">
<a href="https://itunes.apple.com/cn/app/id1047180157">
<div align="center" style="background:url(http://cdn.a0.bnbtrip.com/assets/images/web/2016/04/cup.jpg) no-repeat; width: 100%; height: 100%; background-size: cover;background-position:center;">
</div>
</a>
</body>
</html>

注意<a href=""><div style= "background:url()"></div></a>链接的应用， 即用<div>中的background来做背景， 超链接是点击这个背景图片即跳转, meta标签内容是适应手机屏幕的属性， background 中 no-repeat是背景图片不重复填充， 即只有一张

ExtJS border布局之小案例
zhaohuanzh的博客
01-23 370
前言： layout:‘border’。该布局包含多个字面板，是一个面向应用的UI风格的布局，它将整个容器分为5个部分，分别是east,south, west, north, center,加入到容器中的字面板需要指定region配置这些子元素所在的位置，Border布局会自动把子元素放到布局指定的位置，并且该布局还内建了对面板分割栏的支持。 一．实现界面： 二．实现思路： １－首先确定整体panel为Viewport,layout:"border"(东南西北中　五个区域) ２
