CSS清除默认样式H5端所有项⽬通⽤
将⼿机端设计稿的单位换算成ｒｅｍ，需要在⽂件中加⼊如下⼀段脚本：
<script type="text/javascript">
/*  rem  尺⼨换算  1rem=100px    */
(function (doc, win) {
var docEl = doc.documentElement,
resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize',
recalc = function () {
var clientWidth = docEl.clientWidth;
if (!clientWidth) return;
if(clientWidth>=640){
docEl.style.fontSize = '100px';
}else{
docEl.style.fontSize = 100 * (clientWidth / 750) + 'px';
}
};
if (!doc.addEventListener) return;
win.addEventListener(resizeEvt, recalc, false);
doc.addEventListener('DOMContentLoaded', recalc, false);
})(document, window);
</script>
下⾯的代码在清除默认样式的同时，也解决了H5端的⼀些适配和样式兼容性问题，要将上⾯的ＪＳ代码与下⾯对应的ＣＳＳ适配代码配合来使⽤（有些class类名是平时⾃⼰开发时的⼀些习惯）：
