h5整体页面布局

只要在每个页面加入这段js他会把每个页面平均分成横向25rem，纵向47rem//页面布局

<script>

(function(doc, win) {
    var docEl = doc.documentElement,
        resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize',
        recalc = function() {
            window.clientWidth = docEl.clientWidth;
            if(!window.clientWidth) return;
            docEl.style.fontSize = 30 * (window.clientWidth / 750) + 'px';
            window.base = 30 * (window.clientWidth / 750);
        };
    if(!doc.addEventListener) return;
    win.addEventListener(resizeEvt, recalc, false);
    doc.addEventListener('DOMContentLoaded', recalc, false);
})(document, window);

</script>
