如何避免 CSS Grid 中的图像溢出容器？

Question

我尝试在 CSS Grid 上创建一个高度为 100% 的页面，但是当我将图像放入其容器中并缩小窗口时，内容在我的另一个容器上垂直溢出。它只发生在基于 100vh 的页面上。我只使用 Grid 属性进行了努力，但没有任何效果

有人有解决方案吗？

我当前的代码：https://jsfiddle.net/kxaobqcr/3/ HTML

    <header>
      <div class="type"> <h1>Title</h1> </div>
      <div class="nav">
        <a href="#"> x </a>
        <a href="#"> x </a>
        <a href="#"> x </a>
        <a href="#"> x </a>
        <a href="#"> x </a>
        <a href="#"> x </a>
      </div>
    </header>

    <section class="content">
      <div class="library"> <img src="https://i.pinimg.com/originals/2d/8f/3e/2d8f3ef4a6bac30d0a4c7a44f7b3d574.jpg" alt=""> 
      </div>
    </section>
  </body>

CSS

html,body {
  margin: 0;
  padding: 0;
  height: 100%;
  width: auto;
  font-family: 'Libre Baskerville', serif;
}

body {
  display: grid;
  width: 100vw;
  height: 100vh;
  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: repeat(12, 1fr);
  grid-gap: 10px 10px;
}

header {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: repeat(2, 1fr);
  grid-row: 1/ 3;
  grid-column: 1/ 13;
  grid-gap: 10px 10px;
  background-color: grey;
}

.type {
  display: grid;
  grid-row: 1/ 2;
  grid-column: 1/ 8;
  grid-template-columns: 1fr;
  grid-template-rows: 1fr;
  align-self: center;
  background-color: lightcoral;
}

.nav {
  display: grid;
  grid-row: 2/ 3;
  grid-column: 1/ 8;
  grid-template-columns: repeat(8, 1fr);
  grid-template-rows: 1fr;
  align-self: center;
  background-color: crimson;
}

a {
   color: black;
   text-decoration: none;
   padding: 10px;
 }

img {
  max-width: 100%;
  max-height: 100%;
  object-fit: cover;
}

.content {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: repeat(12, 1fr);
  grid-column: 1/ 13;
  grid-row: 3 / 13;
  grid-gap: 10px 10px;
 }

 .library {
   grid-column: 4/ 10;
   grid-row: 4 / 10;
   justify-self: center;
   align-self: center;
 }

我还在学习网格布局，欢迎提出一些最小化 CSS 代码的建议 :-)

我找到了解决方案。删除 css 代码上的 align-items，溢出问题消失。要使图像居中，只需使用边距：自动。

新代码：https://jsfiddle.net/k1fmodv5/

CSS

html,body {
  margin: 0;
  padding: 0;
  height: 100%;
  width: auto;
  font-family: 'Libre Baskerville', serif;
}

body {
  display: grid;
  width: 100vw;
  height: 100vh;
  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: repeat(12, 1fr);
  grid-gap: 10px 10px;
}

header {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: repeat(2, 1fr);
  grid-row: 1/ 3;
  grid-column: 1/ 13;
  grid-gap: 10px 10px;
  background-color: grey;
}

.type {
  display: grid;
  grid-row: 1/ 2;
  grid-column: 1/ 8;
  grid-template-columns: 1fr;
  grid-template-rows: 1fr;
  align-self: center;
  background-color: lightcoral;
  min-height: 0;
}

.nav {
  display: grid;
  grid-row: 2/ 3;
  grid-column: 1/ 8;
  grid-template-columns: repeat(8, 1fr);
  grid-template-rows: 1fr;
  align-self: center;
  background-color: crimson;
}

a {
   color: black;
   text-decoration: none;
   padding: 10px;
 }

img {
  max-width: 100%;
  max-height: 100%;
  object-fit: cover;
}

.content {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  grid-template-rows: repeat(12, 1fr);
  grid-column: 1/ 13;
  grid-row: 3 / 13;
  grid-gap: 10px 10px;
 }

 .library {
   grid-column: 4/ 10;
   grid-row: 4 / 10;
   margin:auto;
 }

感谢大家的帮助！

我尽量让这个视图变得简单

这是jsfiddle的链接，看一下：https://jsfiddle.net/dupinderdhiman/zum2kxpw/5/

a{
  padding: 10px;
  border-top: 1px solid blue;
  border-bottom: 1px solid blue;
}

img {
  max-width: 100%;
  max-height: 100%;
  object-fit: cover;
}
