html - 使用 flex 和 line-height+vh 时如何对齐尺寸？

Question

我收到了 pretty close to what I want但是我认为 32vh 正在破坏我的体型。

当我使用 img {height: 100%;}它们变得太大了，所以我安定下来 32vh；然而，左右 div 相差几个像素。如果放大一点(按 ctrl+'+')，它会特别明显。它发生在 Firefox 和 chrome 上。我尝试在图像上使用 50% 和 100% 的高度，并在 testB 上放置相对位置，但似乎没有帮助。如何使两个大小相等的高度？我不介意右侧的两个 div 之间是否有额外的像素，但它们必须与左侧的高度相同，即 div a

body * {
  box-sizing: border-box;
  color: white;
}

.test {
  margin: 0 auto;
  position: relative;
  height: 65vh;
  width: 80vw;
  display: flex;
  text-align: center;
}

.testA {
  background-color: black;
  width: 61.5%;
  display: inline-block;
  padding-right: 18px;
  line-height: 65vh;
}

.testB {
  background-color: green;
  flex-grow: 1;
  line-height: 32vh;
  position: relative;
}

.testC {
  background-color: royalblue;
  vertical-align: top;
  margin-bottom: 10px;
}

.testD {
  flex-grow: 1;
  background-color: purple;
  vertical-align: bottom;
  margin-top: 10px;
}

.test img {
  vertical-align: middle;
}

.testA img {
  height: 100%;
}

.testC img {
  vertical-align: top;
  height: 32vh;
}

.testD img {
  vertical-align: bottom;
  height: 32vh;
}

我希望这是你所期望的:

<style>
  body * {
    box-sizing: border-box;
    color: white;
  }
  
  .test {
    margin: 0 auto;
    position: relative;
    height: 65vh;
    width: 80vw;
    display: flex;
  }
  
  .testA {
    background-color: black;
    width: 61.5%;
    display: inline-block;
    padding-right: 18px;
    line-height: 65vh;
    text-align: center;
  }
  
  .testB {
    background-color: green;
    flex-grow: 1;
    display: flex;
    flex-direction: column;
    line-height: 32vh;
    text-align: right;
    position: relative;
  }
  
  .testC {
    display: flex;
    align-items: center;
    justify-content: center;
    background-color: royalblue;
    vertical-align: top;
  }

    align-items: center;
    justify-content: center;
    background-color: purple;
    flex-grow: 1;
    vertical-align: bottom;

  .testA img {
