【问题描述】：
我目前在页面上的元素定位方面遇到了一些问题。全屏时元素居中且不重叠。
但是，当屏幕调整大小时，元素会向左移动并开始重叠
我想知道如何解决这个问题？
这是我的代码：

JS
var player = document.getElementById("player");
let progress = document.getElementById("progress");
let playbtn = document.getElementById("playbtn");
var playpause = function () {
if (player.paused) {
player.play();
} else {
player.pause();
}
}
playbtn.addEventListener("click", playpause);
player.onplay = function () {
playbtn.classList.remove("fa-play");
playbtn.classList.add("fa-pause");
}
player.onpause = function () {
playbtn.classList.add("fa-play");
playbtn.classList.remove("fa-pause");
}
player.ontimeupdate = function () {
let ct = player.currentTime;
current.innerHTML = timeFormat(ct);
///progress
let duration = player.duration;
prog = Math.floor((ct * 100) / duration);
progress.style.setProperty("--progress",prog + "%");
}
function timeFormat(ct) {
minutes = Math.floor(ct / 60);
seconds = Math.floor(ct % 60);
if (seconds < 10) {
seconds = "0"+seconds;
}
return minutes + ":" + seconds;
}
