html - flexbox半侧布局，左侧图像固定

我如何将屏幕的左右半部分固定为固定图像（如导航栏，如果您滚动它们，它们仍然在左侧并且不可滚动）

我正在使用flexbox将屏幕拆分为一半，但是有问题。

图片是可滚动的，不是页面（屏幕）的全高。

我的CSS：

.fo-container {
  display: flex;
  height: 100%;
  justify-content: space-between;
}


.left-half {
    /* The image used */
  background-image: url("http://getwallpapers.com/wallpaper/full/9/9/0/722477-best-barber-wallpapers-1920x1080-samsung-galaxy.jpg");

  /* Center and scale the image nicely */
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  flex: 1;
}

.right-half {
  background-color: white;
  flex: 1;
  align-items: center;
  padding: 1rem;
}

我的HTML：

<div class="fo-container">
    <div class="left-half"></div>
    <div class="right-half"></div>
</div>

最佳答案

首先将容器设置为100vh而不是100%。

可以使用flex属性（flex-basis）中的第三个值来设置两侧的宽度：

flex: 0 0 50%;

右滚动栏可以使用overflow-y来实现。

.fo-container {
  display: flex;
  height: 100vh;
}

.left-half {
  background-image: url("https://picsum.photos/200/300"); /* change back to whatever background image you want */
  background-position: center;
  background-repeat: no-repeat;
  background-size: cover;
  flex: 0 0 50%; /* flex-basis: 50% */
}

.right-half {
  flex: 0 0 50%; /* flex-basis: 50% */
  background-color: white;
  padding: 1rem;
  box-sizing: border-box; /* make sure 50% is still 50% after you add padding */
  overflow-y: auto; /* scrollability here */
}

<div class="fo-container">
  <div class="left-half"></div>
  <div class="right-half">
