Question

嗨，我有一个flexbox布局，其中有一个页眉，内容和页脚。除了图像的缩放比例之外，其他所有功能都可以正常工作。我希望图像在内容的高度上也能缩放，但是出于任何原因页脚都将其重叠。

它是这样的：

body {
  margin: 0;
}

.modal {
  display: flex;
  height: 100vh;
  width: 100vw;
  flex-direction: column;
  background: green;
}

.projectHeadline,
.projectFooter {
  background: yellow;
  height: 100px;
}

.swiper-container {
  display: flex;
  flex: auto;
  margin: auto;
  background: red;
  height: 100%;
}

.swiper-wrapper {
  margin: auto;
  height
  background: black;
}

.swiper-wrapper img {
  display: block;
  width: 100%;
  height: auto;
}

<div class="modal">
  <div class="projectHeadline">Headline</div>
  <div class="swiper-container">
    <div class="swiper-wrapper">
      <img src="http://via.placeholder.com/350x450">
    </div>
  </div>
  <div class="projectFooter">Footer</div>
</div>

您溢出了。您可以像这样纠正它：

    Alert alert = new Alert(AlertType.ERROR);
    alert.setTitle("Error Dialog");
    alert.setHeaderText("Look, an Error Dialog");
    alert.setContentText("Ooops, there was an error!");
    alert.showAndWait();
