垂直调整窗口大小时，Div容器消失

Question

我有一个奇怪的问题，为什么当我垂直调整窗口大小时，我的div容器会缩小/消失并且不遵循正常的网站布局。这是我正在谈论的屏幕截图。

如您所见，红色应该覆盖所有内容，包括内部带有所有颜色的框。这仅在我垂直调整网页大小时发生，我不知道为什么这样做。

这是我的代码：

.main-content {
  display: flex;
  flex-direction: column;
  height: calc(100% - 84px);
}

.main-content-container {
  display: flex;
  flex-direction: column;
  justify-content: center;
  height: 100%;
  background: red;
}

.info-box-container {
  display: flex;
  justify-content: center;
}

.info-box {
  display: flex;
  height: 195px;
  width: 350px;
  background: white;
  margin-right: 15px;
  box-shadow: 0 2px 4px 0 rgba(0, 0, 0, 0.1);
}

.info-box .left-side {
  display: flex;
  flex-direction: column;
  flex: 1;
  background: red;
}

.info-box .top {
  flex: 1;
  display: flex;
  justify-content: center;
  background: yellow;
}

.info-box .top p {
  margin-bottom: 5px;
  background: green;
  font-size: 25px;
  align-self: flex-end;
}

.info-box .bottom {
  flex: 1;
  display: flex;
  justify-content: center;
  background: orange;
}

.info-box .right-side {
  flex: 1;
  background: blue;
}

.info-box:last-child {
  margin: 0;
}

.welcome-msg {
  text-align: center;
  height: auto;
}

.welcome-msg p {
  font-size: 30px;
  font-weight: lighter;
}

<div class="main-content">
  <div class="main-content-container">
    <div class="welcome-msg">
      <p>Welcome, Omar</p>
    </div>
    <div class="info-box-container">
      <div class="info-box">
        <div class="left-side">
          <div class="top">
            <p>500</p>
          </div>
          <div class="bottom">
            <p>Reports</p>
          </div>
        </div>
        <div class="right-side">

        </div>
      </div>
    </div>
  </div>
</div>

谢谢！

您可以将min-height添加到.main-content。在您的情况下，.info-box的高度为195px。将min-height中的.main-content设置为195px，以便在调整屏幕大小时不会缩小到195px以上，即.info-box的大小。

.main-content {
  display: flex;
  flex-direction: column;
  height: calc(100% - 84px);
  min-height: 195px;
}

.main-content-container {
  display: flex;
  flex-direction: column;
  justify-content: center;
  height: 100%;
  background: red;
}

.info-box-container {
  display: flex;
  justify-content: center;
}

.info-box {
  display: flex;
  height: 195px;
  width: 350px;
  background: white;
  margin-right: 15px;
  box-shadow: 0 2px 4px 0 rgba(0, 0, 0, 0.1);
}

.info-box .left-side {
  display: flex;
  flex-direction: column;
  flex: 1;
  background: red;
}

.info-box .top {
  flex: 1;
  display: flex;
  justify-content: center;
  background: yellow;
}

.info-box .top p {
  margin-bottom: 5px;
  background: green;
  font-size: 25px;
  align-self: flex-end;
}

.info-box .bottom {
  flex: 1;
  display: flex;
  justify-content: center;
  background: orange;
}

.info-box .right-side {
  flex: 1;
  background: blue;
}

.info-box:last-child {
  margin: 0;
}

.welcome-msg {
  text-align: center;
  height: auto;
}

.welcome-msg p {
  font-size: 30px;
  font-weight: lighter;
}

<div class="main-content">
  <div class="main-content-container">
    <div class="welcome-msg">
      <p>Welcome, Omar</p>
    </div>
    <div class="info-box-container">
