[转]部分手机网站前端设计经验

1.

（1）强制让文档与设备的宽度保持1：1；

（2）文档最大的宽度比列是1.0（initial-scale初始刻度值和maximum-scale最大刻度值）；

（3）user-scalable定义是否可缩放（0为不缩放），使页面固定设备上面的大小。

下图分别是没有定义viewport和定义viewport在手机上显示的hello world网页。

  

注意：实际测试中发现，HTC G7自身系统浏览器不支持这一条规则，可以对页面进行放大，一旦放大响应的box也随之放大，致使俄页面出现错乱问题，解决方法：定义页面的最小宽度 min-width，body{min-width: 300px;}

2.

使设备浏览网页时对数字不启用电话功能（不一样设备解释不一样，itouch点击数字为存入联系人，iphone为拨打电话），忽略将页面中的数字识别为电话号码。

若须要启用电话功能将telephone=yes便可，具体调用格式能够这样书写代码Call Me，若在页面上面有google maps, iTunes和youtube的连接会在ios设备上打开相应的程序组件。

HTML5标签的使用

HTML5中增长了不少标签，例如：header、nav、footer等，能够实现更丰富的WEB应用程序体验，而且能够减小开发者的工做量。

目前，手机操做系统和浏览器对HTML5的支持还不是很是完善，在使用的时候须要仔细测试。

在手机版合同信息录入系统中，用到了,该标签与text输入域差很少，可是在给该输入域输入内容时，手机键盘为电话号码键盘，以下图所示。

 

利用CSS3边框背景属性

CSS3中增长了许多新的特性，例如：圆角边框、文字投影等等。目前各个主流浏览器对CSS3属性的实现方式不太同样，这就须要用到各类浏览器的前缀。比较经常使用的有：

-webkit-border-image    适用于webkit内核的浏览器  safari  google

-moz-border-image       适用于mozilla浏览器 firefox

以下图所示，是iphone上比较经常使用的web app样式。该网页彻底使用CSS3实现，并未使用任何图片。

块级化a标签

请保证将每条数据都放在一个a标签中，为什么这样作？由于在触控手机上，为提高用户体验，尽量的保证用户的可点击区域较大。

在触控手机上，为提高用户体验，应尽量保证用户的可点击区域较大。所以，尽可能将每条数据都放在一个a标签中。以下图所示，每一个酒店的信息都放在一个a标签中，便于用户点击。

 

自适应布局模式

在编写CSS时，尽可能不要把容器（无论是外层容器仍是内层）的宽度定死。为达到适配各类手持设备，应使用自适应布局模式，这样作可让你的页面在ipad、itouch、ipod、iphone、android、web safarik、chrome都可以正常的显示，无需再次考虑设备的分辨率。
