具有扩展项目及其周围项目的网格布局

Question

尝试创建如下所示的布局：

每个项目都是一个正方形（通过底部填充技术创建）。项目不应重叠。

无论我使用什么grid-area道具，我在使用绿色元素时都遇到麻烦–它在左侧创建空白。

我在JSFiddle上进行了演示– http://jsfiddle.net/f2to1kyw/

甚至不用JS也可以创建这样的布局吗？

.container {
  position: relative;
  display: grid;
  grid-gap: 10px;
  grid-template-columns: repeat(5, 1fr);
}

.item {
  background: tomato;
  width: 100%;
}

.item:before {
  content: '';
  padding-bottom: 100%;
  display: block;
}

.item--big {
  grid-area: 1 / 1 / 3 / 3;
}

.item--green {
  background: #36926A
}

<div class="container">
  <div class="item item--big"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item item--green"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
</div>

Answer 1

Is it even possible to create such layout without JS?

Yes. There are a number of ways of doing this with CSS Grid.

Using the grid-area property:

From MDN:

The grid-area CSS property is a shorthand property for grid-row-start, grid-column-start, grid-row-end and grid-column-end…

So the value of the grid-area property for the green box would be: 2 / 4 / 4 / 6

which is shorthand for:

grid-row-start: 2;
grid-column-start: 4;
grid-row-end: 4;
grid-column-end: 6;

so the CSS rule would be:

.item--green {
  grid-area: 2 / 4 / 4 / 6;
}

.container {
  position: relative;
  display: grid;
  grid-gap: 10px;
  grid-template-columns: repeat(5, 1fr);
}

.item {
  background: tomato;
  width: 100%;
}

.item:before {
  content: '';
  padding-bottom: 100%;
  display: block;
}

.item--big {
  grid-area: 1 / 1 / 3 / 3;
}

.item--green {
  background: #36926A;
  grid-area: 2 / 4 / 4 / 6;
}

<div class="container">
  <div class="item item--big"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item item--green"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
</div>

Using the grid-column / grid-row properties

.container {
  position: relative;
  display: grid;
  grid-gap: 10px;
  grid-template-columns: repeat(5, 1fr);
}

.item {
  background: tomato;
  width: 100%;
}

.item:before {
  content: '';
  padding-bottom: 100%;
  display: block;
}

.item--big {
  grid-column: 1 / span 2;
  grid-row: 1 / span 2;
}

.item--green {
  background: #36926A;
  grid-column: 4 / span 2;
  grid-row: 2 / span 2;
}

<div class="container">

  <div class="item item--big"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item item--green"></div>
  <div class="item"></div>
  <div class="item"></div>
  <div class="item"></div>
</div>

The Relevant Code:

.item--green {
  grid-column: 4 / span 2; /* start at column 4 and span 2 columns  */
  grid-row: 2 / span 2;  /* start at row 2 and span 2 rows */
}
