一、meta的使用

bc平台搭建【企鹅21717-93408】1、<meta name="viewport" content="width=device-width,initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"/>强制让文档的宽度与设备的宽度保持1:1，并且文档最大的宽度比例是1.0，且不允许用户点击屏幕放大浏览。2、winphone系统a、input标签被点击时产生的半透明灰色背景怎么去掉：

<meta name="msapplication-tap-highlight" content="no">

13、忽略页面的数字为电话，忽略email识别 ：

<meta name="format-detection" content="telephone=no, email=no"/>

1二、针对适配等比缩放的方法:

@media only screen and (min-width: 1024px){

　　body{zoom:3.2;}}@media only screen and (min-width: 768px) and (max-width: 1023px) { 　　body{zoom:2.4;}}@media only screen and (min-width: 640px) and (max-width: 767px) { 　　body{zoom:2;}}@media only screen and (min-width: 540px) and (max-width: 639px) { 　　body{zoom:1.68;}}@media only screen and (min-width: 480px) and (max-width: 539px) { 　　body{zoom:1.5;}}@media only screen and (min-width: 414px) and (max-width: 479px) { 　　body{zoom:1.29;}}@media only screen and (min-width: 400px) and (max-width: 413px) { 　　body{zoom:1.25;}}@media only screen and (min-width: 375px) and (max-width: 413px) { 　　body{zoom:1.17;}}@media only screen and (min-width: 360px) and (max-width:374px) { 　　body{zoom:1.125;}}
