html - 不重叠的 CSS 缩放

Question

我需要使用 transform scale(1.3) 来缩放中间的 div。它当然有效，但问题是在缩放后它会与相邻的 div 重叠。是否可以仅使用 CSS 来消除重叠？这是它现在的样子:

但是我想要这样

.main {
  width: 100%;
  height: 500px;
  background-color: gray;
  padding: 100px;
}

.box {
  width: 100px;
  height: 100px;
  background-color: red;
  margin: 2px;
  display: inline-block;
  border: 2px;
  border-style: solid;
  border-color: black;
}

.scaled-box {
  width: 100px;
  height: 100px;
  -webkit-transform: scale(1.3);
  -moz-transform: scale(1.3);
  transform: scale(1.3);
  display: inline-block;
  background-color: green;
  opacity: 0.7;
}

<div class="main">
  <div class="box"></div>
  <div class="scaled-box"></div>
  <div class="box"></div>
</div>

.main {
    width: 100%;
    height: 500px;
    background-color: gray;
    padding: 100px;
    --scale-rate:1.5; /* You can change scale from this line */
}

.box {
    width: 100px;
    height: 100px;
    background-color: red;
    display: inline-block;
    border: 2px;
    border-style: solid;
    border-color: black;
}

.box:first-child{
  margin-right: calc(((100px * var(--scale-rate)) - 100px) / 2); /* 100px is scaled-box width*/
}

.box:last-child{
  margin-left: calc(((100px * var(--scale-rate)) - 100px) / 2); /* 100px is scaled-box width*/
}

.scaled-box {
    width: 100px;
    height: 100px;
    -webkit-transform: scale(var(--scale-rate));
    -moz-transform: scale(var(--scale-rate));
    transform: scale(var(--scale-rate));
    display: inline-block;
    background-color: green;
    opacity: 0.7;
}

<div class="main">
    <div class="box"></div>
    <div class="scaled-box"></div>
    <div class="box"></div>
</div>
