網格列在溢出時延遲調整大小

Question

我有一個2×2CSS網格，它使用固定定位填滿瀏覽器視窗。它看起來像這樣：-----------------||xxxxxxxxxxxxx|-----------------|x|||x |||x|||x||-----------------頂行和左列各自適合其內容且大小為auto。底行和右列分別用於佔用任何剩餘空間並具有大小1fr。東北和西南單元格（圖中充滿了X）都是可滾動的Flex父單元。它們包

為了防止這種情況，網格需要更新其尺寸並考慮捲軸。另一個問題是如何僅使用 css 來做到這一點。我想到為 grid-template-columns 應用 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 來實作：

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;
}
