响应 div 个块

Question

我有 6 个这样的连续块：

在移动版和桌面版中，一切都如我所愿，但是当我将 flex-direction 从 row 更改为 column 时：

在桌面版中，一切正常，但在移动版中，块不是每行 2 个，而是在一列中。我该如何解决？

CSS:

* {
  box-sizing: border-box;
}
img {
  width: auto;
  max-width: 100%;
  height: auto;
  max-height: 100%;
}
.picture-box {
  display: flex;
  flex-direction: row;
  flex-wrap: wrap;
  justify-content: space-between;
  padding: 3rem 1.5rem;
}

.ring {
  flex: 0 0 calc(50% - 10px);
  padding: 20px;
  margin-bottom: 20px;
  border: 1px solid green;
  text-align: center;
}


.thumb {
  display: inline-block;
  max-width: 200px;
  padding: 10px;
  border: 1px solid blue;
}

@media all and (min-width: 1024px) {
  .ring {
    flex: 0 0 calc((100% / 3) - (40px / 3))
  }
}
@media all and (min-width: 1240px) {
  .ring {
    flex: 0 0 calc((100% / 6) - (100px / 6))
  }
}

HTML:

<div class="picture-box">
  <div class="ring">
    <div class="thumb">
      <img src="https://via.placeholder.com/200">
    </div>
  </div>
  <div class="ring">
    <div class="thumb">
      <img src="https://via.placeholder.com/200">
    </div>
  </div>
  <div class="ring">
    <div class="thumb">
      <img src="https://via.placeholder.com/200">
    </div>
  </div>
  <div class="ring">
    <div class="thumb">
      <img src="https://via.placeholder.com/200">
    </div>
  </div>
  <div class="ring">
    <div class="thumb">
      <img src="https://via.placeholder.com/200">
    </div>
  </div>
  <div class="ring">
    <div class="thumb">
      <img src="https://via.placeholder.com/200">
    </div>
  </div>
</div>

Answer 1

如何使用桌面媒体查询来保持 column 布局并使用 flex-direction : row 移动设备和平板电脑？

@media all and (min-width: 1024px) {
  .ring {
    flex: 0 0 calc((100% / 3) - (40px / 3))
  }

  .picture-box {
    flex-direction: column;
  }

}

请使用，https://getbootstrap.com/ 框架。并使用 html 这样的结构，

      <div class="picture-box">
            <div class="row">
                <div class="col-sm-2">
                    <div class="ring">
                        <div class="thumb">
                            <img src="https://via.placeholder.com/200">
                        </div>
                    </div>
                </div>
                <div class="col-sm-2">
                    <div class="ring">
                        <div class="thumb">
                            <img src="https://via.placeholder.com/200">
