        全局定义是指在全局定义里的标签缺省下的样式规则，包括三部分：<br>
        1、HTML5新模板和兼容：包括十二个block新标签、三个inline-block新标签，以及隐藏等其他属性；<br>
        2、全局标记一致性定义：约定html、body、img、p等标签在所有浏览器中一致性定义；<br>
        3、表单一致性定义：约定button、input、checkbox、radio等表单属性在所有浏览器中一致性定义。<br>

article,aside,details,figcaption,figure,footer,header,hgroup,main,nav,section,summary{display:block;}

</tr>
<tr>
    <td>
<span class="z-text-prewrap z-pre">
audio:not([controls]){display:none;height:0;}

为防止主流浏览器中，显示"不带控制按钮的音频模块"这一问题。以及解决iOS5移动端显示多余高度的兼容性问题。
</span>
    </td>
</tr>

    <td class="zi-px18">四、有隐藏属性或标记为模板的的设置为隐藏</td>

</tr>
<tr>
    <td>
<span class="z-text-prewrap z-pre">
svg:not(:root){overflow:hidden;}

只支持一个根元素如(&lt;svg&gt;&lt;/svg&gt;)，除了&lt;svg&gt;内部的，其他的都不显示

*:before,*:after{-webkit-box-sizing:border-box;-moz-box-sizing:border-box;box-sizing:border-box;}

默认所有元素含插入内容前后宽高设置采用border-box方式，即宽高包括border和padding，向内扩充

1、设置全局字体，防止一些设备上字体随屏幕放大而改变字体大小,如webkit的Safari
2、指定文档隐藏X轴滚动条，Y轴滚动条自动
3、当屏幕横坚切换时字体大小调整和以前一样
4、iOS下链接点中是修改为黑色
