如何让溢出自动与 css 网格一起工作？

Question

在左列下面的代码片段中 "accordion" 应该可以在溢出时滚动，而不是整个页面。目前看起来整个页面都可以滚动，即使我只是想让手风琴溢出。

如果需要，内容页面应该会溢出，但不会溢出整个页面

/*Page Layout*/

.wrapper {
  display: grid;
  grid-gap: 10px;
  grid-template-columns: [col] 225px [col] 1fr  ;
  grid-template-rows: [row] 1fr;
  background-color: #fff;
  color: #444;
  padding-bottom: 20px;
}

.content{
  grid-column: 2;
  grid-row: row 1 ;

}
.myaccordion{;
  grid-row: row 1 ;
  grid-column: 1;
  background-color:  #da516e;
  height: 100vh;
  overflow: auto;
}

更新：

填充是有目的的，因为它提高了页面底部的手风琴。原因是，如果您滚动手风琴菜单中的某个项目，浏览器会显示一个 link，这会阻碍菜单中最后一项的视图。

Answer 1

浏览器通常默认为 body 元素提供 8 像素的边距。

所以首先重置：

body { margin: 0; }

其次，您的网格容器具有底部填充，它似乎没有做任何事情，除了导致视口具有垂直滚动。删除：

.wrapper {
  display: grid;
  grid-gap: 10px;
  grid-template-columns: [col] 225px [col] 1fr  ;
  grid-template-rows: [row] 1fr;
  background-color: #fff;
  color: #444;
  /* padding-bottom: 20px; */
}
