expected result

我试图使用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大小，文本div可以滚动。 我可以通过JS / jQuery代码（现在评论）来做，但不知道纯CSS做到了。 任何人都可以帮我解决这个问题吗？ 谢谢。

要使其工作，您需要在最后一个弹性项目中添加一个额外的元素，位于绝对位置。

.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>
