將video設置為屏幕大小，覆蓋其他元素，想到這種操作我也是震驚的

function() {
                let startIcon = document.getElementById(‘start-icon‘);
                startIcon.src = ‘/static/icon/icon-ctrl-stop.png‘;
                let myVideo = document.getElementById(‘myVideo‘);
                myVideo.controls = ‘auto‘;

                let w 
 
= document.documentElement.clientWidth || document.body.clientWidth;
                let h = document.documentElement.clientHeight || document.body.clientHeigth;
                let cha = Math.abs(h - w) / 2;
                myVideo.width = h;
                myVideo.height = w;
                myVideo.style.zIndex 
 
= 2000;
                myVideo.style.top = 0
                myVideo.style.transform = ‘translate(-‘ + cha + ‘px,‘ + cha + ‘px) rotate(90deg)‘;

            }
