由于某些奇怪的原因,添加align-items: flex-end甚至flex-start破坏了粉红色弯曲项目的良好滚动溢出行为,因为它比容器高度高。
如果这是预期的行为,请帮助我保留滚动,即使在弯曲端对齐中也是如此。
这是演示。
.slidesWrap {
  display: flex;
  flex-direction: row;
  align-items: flex-end;
}
.slide {
  overflow: auto;
  flex: 1;
}<div style="width: 200px; position:relative; top: 200px; background: silver;">
  <div class="slidesWrap" style="height:200px">
    <div class="slide">
      <div style="height:300px; width:100%; background: pink;">content</div>
    </div>
    <div class="slide">
      <div style="height:30px; width:100%; background: green;">content</div>
    </div>
  </div>
</div>另一种方法可以是: max-height:100%;
.slidesWrap {
  display: flex;
  flex-direction: row;
  align-items: flex-end;
}
.slide {
  overflow: auto;
  flex: 1;
  max-height:100%;
}<div style="width: 200px; position:relative; top: 200px; background: silver;">
  <div class="slidesWrap" style="height:200px">
    <div class="slide">
      <div style="height:300px; width:100%; background: pink;">content</div>
    </div>
    <div class="slide">
      <div style="height:30px; width:100%; background: green;">content</div>
    </div>
  </div>
</div>.slidesWrap {
  display: flex;
}
.slide {
  overflow: auto;
  flex: 1;
  max-height:100%;
  margin-top:auto;
}<div style="width: 200px; position:relative; top: 200px; background: silver;">
  <div class="slidesWrap" style="height:200px">
    <div class="slide">
      <div style="height:300px; width:100%; background: pink;">content</div>
    </div>
    <div class="slide">
      <div style="height:30px; width:100%; background: green;">content</div>
    </div>
  </div>
</div>或使用柱流:
.slidesWrap {
  display: flex;
  flex-flow: column wrap;
  justify-content:flex-end
}
.slide {
  overflow: auto;
  width:50%;
}   <div style="width: 200px; position:relative; top: 200px; background: silver;">
        <div class="slidesWrap" style="height:200px">
            <div class="slide">
                <div style="height:300px; width:100%; background: pink;">content</div>
            </div>
            <div class="slide">
                <div style="height:30px; width:100%; background: green;
">content</div>
            </div>
        </div>
</div>align-items和属性align-self显然破坏了滚动功能。
幸运的是,有一个简单而干净的替代方案:弹性auto边距。
flex-row {
  display: flex;
}
.slide {
  overflow: auto;
  flex: 1;
  display: flex;
}
.slide > div {
  margin-top: auto; /* pin items to bottom */
}<div style="width: 200px; background: silver;">
  <flex-row class="slidesWrap" style="height:200px">
    <div class="slide" style="">
      <div style="height:300px; width:100%; background: pink;"></div>
    </div>
    <div class="slide" style="">
      <div style="height:30px; width:100%; background: green;"></div>
    </div>
  </flex-row>
