html - 将宽度设置为 100% 以上后，div 水平向右移动

Question

我目前正在一个网站上使用已经编程的滑块。今天我想稍微重构一下页面，当我将滑块的 div 设置为超过 100% 的宽度时，div 一直向右移动......所以 f.ex。120% 中的 20% 被添加到右侧，并且 div 不再放置在页面的中心。

这是正常的吗？如何保持 div 居中？div 的 id 是“之前”。

<style>

  margin: 20px auto;
  text-align: center;

#beforeafter {
  width: 150%;
  max-width: 150%;
  margin: 0 auto;
}
