rem.js配置:(width 为750  转换750px == 7.5rem)

// 自适应rem
(function (doc, win) {
    var docEl = doc.documentElement,
        resizeEvt = ‘orientationchange‘ in window ? ‘orientationchange‘ : ‘resize‘,
        recalc = function () {
            var clientWidth = docEl.clientWidth;
            if (!clientWidth) return;
            if(clientWidth>=750){
                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);

meta 头部设置:

 <!--主要I是强制让文档的宽度与设备宽度保持1:1,最大宽度1.0,禁止屏幕缩放。-->
    <meta content="width=device-width,initial-scale=1.0,maximum-scale=1.0,user-scalable=no" name="viewport">
    <!--这个也是iphone私有标签,允许全屏浏览。-->
    <meta content="yes" name="apple-mobile-web-app-capable">
    <!--iphone的私有标签,iphone顶端状态条的样式。-->
    <meta content="black" name="apple-mobile-web-app-status-bar-style">
    <!--禁止数字自动识别为电话号码,这个比较有用,因为一串数字在iphone上会显示成蓝色,样式加成别的颜色也是不生效的。-->
    <meta content="telephone=no" name="format-detection">
    <!--禁止email识别-->
    <meta content="email=no" name="format-detection">
