低浏览器分辨率下网页底部的白色 space（CSS-Grid 布局）

Question

我一直在尝试使用 CSS-Grid 制作简单的网站布局。一切工作正常并且响应迅速，但是当我将浏览器最小化到非常小的分辨率时，滚动条出现并且 css-grid 停止在整个页面高度上延伸，导致底部出现空白 space。

要理解我的意思，只需运行我插入的代码段，因为它以较低的高度 window 打开。我还上传了它在我的浏览器上显示的图片。

正常身高的显示方式：

当我降低身高时会发生什么：

我试过 overflow 和 min-height，但无法解决。这并不是一个真正的关键问题，但我真的很想知道它为什么会发生。谢谢！

body, html{
  height: 100vh;
  min-height: 100vh;
  min-width: 300px;
  margin: 0;
  padding: 0;
}

.grid-container-1{
  height: 100vh;
  min-height: 100vh;
  min-width: 300px;
  margin: 0;
  padding: 0;
  display: grid;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-template-rows: 8% 70% auto 8% ;
  grid-template-areas:
  "header1 header1 header1 header1"
  "Cover Cover Cover Cover"
  "Project Project Project Project"
  "Footer Footer Footer Footer"
}

.header1{
  grid-area: header1;
}

.cover{
  grid-area: Cover;
}

.Project{
  grid-area: Project;
}

.Footer{
  grid-area: Footer;
}

.zone {
    cursor:pointer;
    color:#FFF;
    font-size:2em;
    border-radius:4px;
    border:1px solid #bbb;
    transition: all 0.3s linear;

Answer 1

你的字体对于最后一行的高度来说太大了，它溢出了它的容器。

其中一个解决方案是将最后一行的大小更改为 1fr:

body, html{
  height: 100vh;
  min-height: 100vh;
  min-width: 300px;
  margin: 0;
  padding: 0;
}

.grid-container-1{
  height: 100vh;
  min-height: 100vh;
  min-width: 300px;
  margin: 0;
  padding: 0;
  display: grid;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-template-rows: 8% 70% auto 1fr;
  grid-template-areas:
  "header1 header1 header1 header1"
  "Cover Cover Cover Cover"
  "Project Project Project Project"
  "Footer Footer Footer Footer"
}

.header1{
  grid-area: header1;
}

.cover{
  grid-area: Cover;
}

.Project{
  grid-area: Project;
}

.Footer{
  grid-area: Footer;
}

.zone {
    cursor:pointer;
    color:#FFF;
    font-size:2em;
    border-radius:4px;
    border:1px solid #bbb;
    transition: all 0.3s linear;
}

.zone:hover {
    -webkit-box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
    -moz-box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
    -o-box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
    box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
}

Answer 2

当您的视口太小无法容纳您的页眉和页脚时，您的文本大小会溢出 - 作为 quick fix 你可以添加 overflow: hidden 到 zone 到 在较小的屏幕上解决 - 请看下面的演示：

body, html{
  height: 100vh;
  min-height: 100vh;
  min-width: 300px;
  margin: 0;
  padding: 0;
}

.grid-container-1{
  height: 100vh;
  min-height: 100vh;
  min-width: 300px;
  margin: 0;
  padding: 0;
  display: grid;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-template-rows: 8% 70% auto 8% ;
  grid-template-areas:
  "header1 header1 header1 header1"
  "Cover Cover Cover Cover"
  "Project Project Project Project"
  "Footer Footer Footer Footer"
}

.header1{
  grid-area: header1;
}

.cover{
  grid-area: Cover;
}

.Project{
  grid-area: Project;
}

.Footer{
  grid-area: Footer;
}

.zone {
    cursor:pointer;
    color:#FFF;
    font-size:2em;
    border-radius:4px;
    border:1px solid #bbb;
    transition: all 0.3s linear;
    overflow: hidden; /* ADDED */
}

.zone:hover {
    -webkit-box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
    -moz-box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
    -o-box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
    box-shadow:rgba(0,0,0,0.8) 0px 5px 15px, inset rgba(0,0,0,0.15) 0px -10px 20px;
}

因为文字溢出元素不是很有用，你需要调整你的header和[=34的高度=]footer 在你的 grid-template-rows 中的值类似于 grid-template-rows: 3em 1fr auto 3em:

body, html{
  height: 100vh;
  min-height: 100vh;
  min-width: 300px;
  margin: 0;

  grid-template-rows: 3em 1fr auto 3em; /* CHANGED */
  grid-template-areas:
  "header1 header1 header1 header1"
