前端動態設定html中font-size大小


(function (doc, win) {
var docEl = doc.documentElement || doc.body,
// 重置事件(旋轉豎屏)
resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize',
recalc = function () {
var clientWidth = docEl.clientWidth;
if (!clientWidth) return;
docEl.style.fontSize = 10 * (clientWidth / 750) + 'px';
console.log(docEl.style.fontSize);
};
if (!doc.addEventListener) return;
win.addEventListener(resizeEvt, recalc, false);
doc.addEventListener('DOMContentLoaded', recalc, false);
})(document, window);
