为什么我不能在以下方案中对齐 div/为什么最后一个容器不可见?

Why can't I align divs in the following scheme / why is the last container not visible?

我想在另一个父容器中对齐七个 div,除了第一个和最后一个容器外,它们都应该具有相同的高度(与父容器一样)和宽度。

我试过类似的东西:

HTML

<div id="weatherBar">
  <div class="arrow"></div>
  <div class="table-wrapper">
    <div>1</div>
  </div>
  <div class="table-wrapper">
    <div>2</div>
  </div>
  <div class="table-wrapper">
    <div>3</div>
  </div>
  <div class="table-wrapper">
    <div>4</div>
  </div>
  <div class="table-wrapper">
    <div>5</div>
  </div>
  <div class="arrow"></div>
</div>

CSS

div#weatherBar {
  position: relative;
  width: 60vw;
  max-width: 60vw;
  height: 10vh;
  left: 50%;
  transform: translateX(-50%);
  background-color: rgb(255, 255, 255);
  overflow: hidden;
  margin-top: 10vh;
}

div#weatherBar div.table-wrapper {
  min-height: 10vh;
  max-height: 10vh;
  min-width: 10vw;
  max-width: 10vw;
  border: solid 0.5px blue;
  float: left;
  overflow: hidden;
}

div#weatherBar div.arrow {
  min-height: 10vh;
  max-height: 10vh;
  min-width: 5vw;
  max-width: 5vw;
  float: left;
  overflow: hidden;
  background-color: red;
}

但是最后的 div 没有出现(我附上了图片),我不知道为什么。你能帮帮我吗?

提前致谢! :-)

元素的 border 默认不包含在元素的 width 中,因为 box-sizing 默认为 content-box

将其更改为 border-box,以便在 width 包含 边框,使用:

* {
  box-sizing: border-box;
}

参见下面的演示:

* {
  box-sizing: border-box;
}
div#weatherBar {
  position: relative;
  width: 60vw;
  max-width: 60vw;
  height: 10vh;
  left: 50%;
  transform: translateX(-50%);
  background-color: rgb(255, 255, 255);
  overflow: hidden;
  margin-top: 10vh;
}

div#weatherBar div.table-wrapper {
  min-height: 10vh;
  max-height: 10vh;
  min-width: 10vw;
  max-width: 10vw;
  border: solid 0.5px blue;
  float: left;
  overflow: hidden;
}

div#weatherBar div.arrow {
  min-height: 10vh;
  max-height: 10vh;
  min-width: 5vw;
  max-width: 5vw;
  float: left;
  overflow: hidden;
  background-color: red;
}
<div id="weatherBar">
  <div class="arrow"></div>
  <div class="table-wrapper">
    <div>1</div>
  </div>
  <div class="table-wrapper">
    <div>2</div>
  </div>
  <div class="table-wrapper">
    <div>3</div>
  </div>
  <div class="table-wrapper">
    <div>4</div>
  </div>
  <div class="table-wrapper">
