Flexbox-在小屏幕上拆分屏幕 [英] Flexbox - screen splitting on small screens

问题描述

我在Codepen上找到了示例，该屏幕将屏幕分成了两半.

I have found an example on Codepen which splits the screen in two halves.

当高度小于宽度时，如何使示例垂直分割屏幕?我想在小型设备上更好地利用屏幕区域，因为在我看来，一个狭窄的长矩形看起来要比一个近似正方形的矩形差.

How to make the example divide the screen vertically when the height is smaller than the width? I want to utilize the screen area on small devices better, because in my opinion a narrow long rectangle looks worse than a nearly square rectangle.

.leftside, .rightside {
height:50vh;
width:100%;
color:#fff;
font-size:40px;
}

@media screen and (min-width:768px)
{
.leftside, .rightside {
    height:100vh;
}
}

推荐答案

您可以使用纵横比->

You can do this with aspect-ratio -> https://developer.mozilla.org/en-US/docs/Web/CSS/@media/aspect-ratio

html,
body {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100%;
}

.container {
  display: flex;
  border: 5px solid green;
  flex-flow: row nowrap;
  height: 100%;
}

.container>div {
  flex: 1;
  height: 100vh;
  color: white;
  font-size: 40px;
}

.container>.leftside {
  background: red;
}

.container>.rightside {
  background: blue;
}

@media (min-aspect-ratio: 9/8) {
  .container {
    display: flex;
    border: 5px solid yellow;
    flex-flow: column nowrap;
  }
  .container>div {
    height: 50vh;
  }
}

<div class="container">
  <div class="leftside">left</div>
  <div class="rightside">right</div>
</div>
