网格列在溢出时延迟调整大小

Question

我有一个2×2CSS网格，它使用固定定位填充浏览器视口。它看起来像这样：-----------------||xxxxxxxxxxxxx|-----------------|x|||x|||x|||x||-----------------顶行和左列各自适合其内容并且大小为auto。底行和右列分别用于占用任何剩余空间并具有大小1fr。东北和西南单元格（图中充满了X）都是可滚动的Flex父单元。它们包

为了防止这种情况，网格需要更新其尺寸并考虑滚动条。另一个问题是如何仅使用 css 来做到这一点。我想到为 grid-template-columns 应用 animation，它似乎有效：

* {
  box-sizing:border-box;
}

#grid {
  position: fixed;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  display: grid;
  grid-template-columns: auto 1fr;
  grid-template-rows: auto 1fr;
  animation: grid 200ms;
}

@keyframes grid {
  to {
    grid-template-columns: auto 2fr;
  }
}

#nw {
  background-color: green;
}

.scrollable {
  display: flex;
}

#ne {
  background-color: red;
  flex-direction: row;
  overflow-x: auto;
}

#sw {
  background-color: yellow;
  flex-direction: column;
  overflow-y: auto;
  scrollbar-color: darkgray #666666;
  scrollbar-width: thick;
}

#se {
  background-color: blue;
}

.box {
  width: 4em;
  height: 4em;
  margin: 5px;
  border-radius: 5px;
  background-color: black;
  flex-shrink: 0;
}

.scrollable::-webkit-scrollbar {
  height: 10px;
  width: 10px;
}

.scrollable::-webkit-scrollbar-thumb {
  background: darkgray;
}

.scrollable::-webkit-scrollbar-track {
  background: #666666;
}

如果你想用 JavaScript 来实现：

setTimeout(() => grid.style.gridTemplateColumns = 'auto 2fr', 200)

* {
  box-sizing:border-box;
}

#grid {
  position: fixed;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  display: grid;
  grid-template-rows: auto 1fr;
  grid-template-columns: auto 1fr;
}

#nw {
  background-color: green;
}

.scrollable {
  display: flex;
}

#ne {
  background-color: red;
  flex-direction: row;
  overflow-x: auto;
}

#sw {
  background-color: yellow;
  flex-direction: column;
  overflow-y: auto;
  scrollbar-color: darkgray #666666;
  scrollbar-width: thick;
}

#se {
  background-color: blue;
}

.box {
  width: 4em;
  height: 4em;
  margin: 5px;
  border-radius: 5px;
  background-color: black;
  flex-shrink: 0;
}

.scrollable::-webkit-scrollbar {
  height: 10px;
  width: 10px;
}

.scrollable::-webkit-scrollbar-thumb {
  background: darkgray;
}

.scrollable::-webkit-scrollbar-track {
  background: #666666;
}
