行之间的Flexbox边距（margin-top：-xx）

Question

它应该如何工作（六边形水平和垂直之间的空间）：

但是当我添加一些元素（或调整浏览器窗口大小）时，flexbox会自动重新缩放所有六边形，但不会重新缩放边距。

我想创建完整的响应（自动调整大小）六边形区域。我可以使用传统的媒体查询来完成它，但我需要创建更灵活的页面。

.row {
    display: flex !important;
}
.mx-1 {
    margin-right: .25rem !important;
    margin-left: .25rem !important;
}
.mr-1 {
    margin-right: .25rem !important;
}
.ml-1 {
    margin-left: .25rem !important;
}
.mt--5 {
    margin-top: -2.8rem !important;
}
.sh.v-hidden .sh-e .sh-c {
  visibility:hidden !important;
}
.sh.sh-hexagon.sh-4 {
    width: 180px;
    height: 207px;
}
.sh.sh-hexagon.sh-2 {
    width: 90px;
    height: 103.5px;
}
.sh.sh-hexagon {
    width: 40px;
    height: 46px;
}
.sh {
    position: relative;
    visibility: hidden;
    overflow: hidden;
}
.sh.sh-hexagon .sh-e {
    transform: rotate(60deg);
}
.sh .sh-e, .sh .sh-e .sh-c {
    position: relative;
    visibility: hidden;
    overflow: hidden;
    width: 100%;
    height: 100%;
    min-height: 100%;
    max-height: 100%;
    min-width: 100%;
    max-width: 100%;
}
.sh.sh-hexagon .sh-e .sh-c {
    transform: rotate(-120deg);
    background: red;
}
.sh .sh-e .sh-c {
    visibility: visible !important;
}
