解决uc浏览器不支持vw单位的方法

插入下段代码，使用rem来代替vw

<script type="text/javascript">
             (function (doc, win) {
            var docEl = doc.documentElement,
                resizeEvt = ‘orientationchange‘ in window ? ‘orientationchange‘ : ‘resize‘,
                recalc = function () {
                    var clientWidth = docEl.clientWidth;
                    if (!clientWidth) return;
                       docEl.style.fontSize =  (clientWidth / 100) + ‘px‘; 
                };
            if (!doc.addEventListener) return;
            win.addEventListener(resizeEvt, recalc, false);
            doc.addEventListener(‘DOMContentLoaded‘, recalc, false);
        })(document, window);
    </script>
