html - 如何在不失去响应能力的情况下使背景图像正确适合板内

Question

我有代码，其中有类框，我已将 backgroundimage 给 class box box1。

我的问题 是图像没有正确地放入板中。

当我重新调整窗口时，它向上移动。

如何改正。

如何使图像正确地适合板内 而不失去响应能力？

这是执行此操作的方法，当我尝试使其适合板内时，它不仅适合盒子内，而且还失去了响应能力..

当它尝试调整窗口大小时图像向上移动..

html, body {
 background-image:url(https://i.ibb.co/K7mpxZG/background9.jpg);
 background-repeat: no-repeat;
 background-size: cover;
 width:100%;
 height:100%;
 overflow: hidden;
 background-size: 100vw 100vh;
}

#box1 {
  position: absolute;
  top: 55.3vh;
  left: -19.98vw;
  cursor: pointer;
  border:px solid #0066CC;
  background-repeat: no-repeat;
  background-size: cover;
}

#box1 p {
  width: 10.0vw;
 height: 1.0vh;
  border-radius: 25%;
}


#container {
  white-space: nowrap;
  border:px solid #CC0000;
}

.containerr {
  border: px solid #FF3399;
}

.container2 {
  width: 50.1vw;
  position: fixed;
  top: 10.5vh;
  left: 30.5vw;
}

.box p {
  font-size: calc(2vw + 10px);
}


.hidden{
  visibility: hidden;
}

p {
  font: "Courier New", Courier, monospace;
  font-size: 5vw;
  color: blue;
  text-align: center;
}

<div class="container2">
  <div class="containerr">
    <div class="pic" id="content">
      <div id="container">
      
        <div class="box box1" id="box1"  style="background-image:url(https://picsum.photos/200/300);">
          <p name="values" id="name1" class="hidden"></p>
        </div>

我认为你处理这个问题的方式是错误的。相反，我会从主背景中提取 board 元素并将其单独用作一个元素:

html {
  background: #afffdc;
}

#container {
  position: fixed;
  bottom: 0;
  left: 100px;
  background: url(/image/CM15R.jpg) top/contain no-repeat;
  height: 50vh;
  width: 29vh;
  max-width: 20vw;
  max-height: 35vw;
}

.box {
  padding-top: 173%;
  background: url(https://picsum.photos/200/300) 50% 5%/86% 27% no-repeat;
}

<div id="container">
  <div class="box">
  </div>
</div>

更新

这里是透明版

html {
  background: linear-gradient(to right,pink, lightblue);
}

#container {
  position: fixed;
  bottom: 0;
  left: 100px;
  background: url(/image/ctB0T.png) top/contain no-repeat;
  height: 50vh;
  width: 29vh;
  max-width: 20vw;
  max-height: 35vw;
}

.box {
  padding-top: 173%;
  background: url(https://picsum.photos/200/300) 50% 5%/86% 27% no-repeat;
}

<div id="container">
  <div class="box">
  </div>
</div>
