rem布局非常簡單,首頁你只需在頁面引入這段原生js代碼就可以了
- (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);
復(fù)制代碼
