将 CSS 网格与变换相结合

Question

有没有什么方法可以将 CSS 网格与转换结合起来以围绕网格布局移动 div？

例如，如果用户单击 B 框（它会展开以占据其当前持有的 space 以及 C 和 F 框），我如何使用转换将 C 和 F 滑出新占用 space 并进入 space 当前网格内未占用？

代码如下：

.grid-wrapper {
  display: grid;
  grid-template-columns: repeat(5, 18% 20px);
  grid-template-rows: repeat(3, 30% 20px);
  height: 95vh;
  width: 95vw;
}

<div class="grid-wrapper">
  <div class="box a">A</div>
  <div class="box b">B</div>
  <div class="box c">C</div>
  <div class="box d">D</div>
  <div class="box e">E</div>
  <div class="box f">F</div>
  <div class="box g">G</div>
  <div class="box h">H</div>
</div>

CSS 网格规范提供了大量用于调整布局的属性和方法。

要调整任何网格项目的大小和位置，您可以使用定义的位置（相对于自动位置）。

这里有一些例子：

.grid-wrapper {
  display: inline-grid;
  grid-template-columns: repeat(3, 75px);
  grid-template-rows: repeat(3, 75px);
  grid-auto-rows: 75px;
  grid-auto-columns: 75px;
  grid-gap: 10px;
  padding: 10px;
  border: 1px solid black;
}

.a {
  grid-row: 1 / 2;
  grid-column: 1 / 2;
}

.a:hover {
  grid-column: 1 / 4;
  background-color: orange;
}

.b:hover {
  grid-row: 1 / 4;
  grid-column: 1 / 3;
  background-color: aqua;
}

.c:hover~.box {
  grid-column: 1 / 4;
  background-color: pink;
}

.h:hover {
  grid-column-end: span 2;
  background-color: green;
}

.box {
  background-color: lightgreen;
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
}

<div class="grid-wrapper">
  <div class="box a">A<br>hover</div>
  <div class="box b">B<br>hover</div>
  <div class="box c">C<br>hover</div>
  <div class="box d">D</div>
  <div class="box e">E</div>
  <div class="box f">F</div>
  <div class="box g">G</div>
  <div class="box h">H<br>hover</div>
</div>

关于你这部分问题：

How could I use transforms to slide C and F out of the newly occupied space and into space currently unoccupied within the grid?

Grid 规范实际上提供了一种实现此确切行为的方法。

在 grid-auto-flow: dense 中，网格自动放置算法将使用适合的项目填充未占用的单元格。

7.7. Automatic Placement: the grid-auto-flow property

Grid items that aren’t explicitly placed are automatically placed into an unoccupied space in the grid container by the auto-placement algorithm.

grid-auto-flow controls how the auto-placement algorithm works, specifying exactly how auto-placed items get flowed into the grid.

dense

If specified, the auto-placement algorithm uses a “dense” packing algorithm, which attempts to fill in holes earlier in the grid if smaller items come up later. This may cause items to appear out-of-order, when doing so would fill in holes left by larger items.

在下面的示例中，grid-auto-flow: dense 在悬停时激活。

.grid-wrapper {
  display: inline-grid;
  grid-template-columns: repeat(5, 50px);
  grid-template-rows: repeat(3, 50px);
  grid-auto-rows: 50px;
  grid-auto-columns: 50px;
  grid-gap: 10px;
  padding: 10px;
  border: 1px solid black;
}

.grid-wrapper:hover {
  grid-auto-flow: dense;
}

.a, .h {
  grid-column-end: span 2;
}

.b, .e {
  grid-row-end: span 2;
}

.f {
  grid-row-end: span 2;
  grid-column-end: span 2;
}

.box {
  background-color: lightgreen;
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
}

.grid-wrapper:hover .g,
.grid-wrapper:hover .h {
  background-color: orange;
}

<div class="grid-wrapper">
  <div class="box a">A</div>
  <div class="box b">B</div>
  <div class="box c">C</div>
  <div class="box d">D</div>
  <div class="box e">E</div>
  <div class="box f">F</div>
  <div class="box g">G</div>
  <div class="box h">H</div>
</div>
