移动端自适应布局 使用方法：元素尺寸/100 = rem
<script> (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 / 640) + 'px'; } }; if (!doc.addEventListener) return;
win.addEventListener(resizeEvt, recalc, false);
doc.addEventListener('DOMContentLoaded', recalc, false);
})(document, window);
