如何缩放到背景而不是其子元素

Question

我想缩放到背景图像并制作动画，但这不是我想要的结果，因为所有子元素都已设置动画和缩放，在悬停时我只想设置动画和缩放到背景部分，我不确定，但我认为是 html 结构

CSS

.laboratorio_container
{
   padding: 2em;
}

.fondo_laboratorio{
  color: white;
  background-image: url(/img/laboratorios/lab1.jpeg);
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  height: 18em;
  display: flex;
  align-items: center;
}

.fondo_laboratorio:hover{
  transition: all .5s;
  transform: scale(120%);
  -webkit-transform: scale(120%);
  -moz-transform: scale(120%);
  -ms-transform: scale(120%);
  -o-transform: scale(120%);
  -webkit-transition: all .5s;
  -moz-transition: all .5s;
  -ms-transition: all .5s;
  -o-transition: all .5s;
}

.laboratorio_container
{
  background-color:rgb(0,0,0,.5);
}

HTML

可以通过多种方式完成。我可以建议两种简单的方法。例如，只需更改背景图片的大小或使用 pseudo-element 过渡在悬停时放大。

Using transition, and background-size

.fondo_laboratorio {
  color: white;
  height: 18em;
  display: flex;
  align-items: center;
}

.laboratorio_container {
  padding: 2em;
  background-color: rgb(0, 0, 0, .5);

  background-image: url('https://picsum.photos/640/360');
  background-position: center;
  background-repeat: no-repeat;
  background-origin: center;
  background-size: 100%;
  transition: background-size .5s;

}

.laboratorio_container:hover {
  background-size: 120%;
}

<div class="container">
  <div class="row fondo_laboratorio">
    <div class="col laboratorio_container">
      <div class="row ms-2">
        <h1 class="p-0">Laboratorios</h1>
      </div>
      <div class="row mb-3 ms-2">

Using transition, and pseudo-element ::before or ::after

.fondo_laboratorio {
  color: white;
  height: 18em;
  display: flex;
  align-items: center;

}

.laboratorio_container {
  padding: 2em;

  /* this */
  position: relative;
  overflow: hidden;
}

.laboratorio_container::before {
  content: '';
  position: absolute;
  left: 0;
  right: 0;
  bottom: 0;
  top: 0;
  z-index: -1;
  background-image: url('https://picsum.photos/640/360');
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  transition: transform .5s;

}

.laboratorio_container:hover::before {
  transform: scale(120%);
}

.laboratorio_container {
  background-color: rgb(0, 0, 0, .5);
}

<div class="container">
  <div class="row fondo_laboratorio">
