我正在尝试使用 CSS 使文本 div (.item:last-child) 与图像 div (.item:first-child) 的高度相同，图像宽度可以适应不同的屏幕尺寸，文本div 可以滚动。我可以通过 JS/jQuery 代码(现在评论)来做到这一点，但不知道通过纯 CSS 来做到这一点。谁能帮我解决这个问题？谢谢。

为此，您需要在最后一个 flex 元素中添加一个绝对定位的额外元素。

.container {
  display: flex;
  justify-content: center;
}

.item:first-child {
  width: 40%;
  background: pink;
  padding: 10px;
  margin: 10px;
  height: min-content;
}

.item:last-child {
  position: relative;
  width: 20%;
  margin: 10px;
  padding: 10px;
  background: pink;
}

.item:last-child .scroll {
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  overflow: auto;
}

<div class="container">
  <div class="item">
    <img src="https://www.w3schools.com/css/img_fjords.jpg" width="100%">
  </div>
  <div class="item">
    <div class="scroll">
      <p>This is the test paragraph.This is the test paragraph.This is the test paragraph.This is the test paragraph.This is the test paragraph.</p>
      <p>This is the test paragraph.This is the test paragraph.This is the test paragraph.This is the test paragraph.This is the test paragraph.</p>
      <p>This is the test paragraph.This is the test paragraph.This is the test paragraph.This is the test paragraph.This is the test paragraph.</p>
    </div>
  </div>
</div>
