Question

尝试使用css网格实现下图中的重复模式:

尝试使用CSS网格,请参阅代码笔

.parent {
  display: grid;
  grid-gap: 20px;
  direction: rtl;
  padding-bottom: 20px;
}

.item--img-cont img {
  width: 100%;
}

.item--text-cont {
  color: white;
}

.item {
  background: black;
}


/*START:Desktop Style */

@media screen and (min-width:1280px) {
  .parent {
    grid-template-columns: 1fr 1fr 1fr 1fr;
    grid-template-rows: 1fr 1fr;
  }
  .item:nth-child(10n+1) {

我无法实现第一个模式.

它仅在我给出grid-row-start属性的硬编码值时才起作用.

注意:不要更改DOM结构.在此先感谢您的帮助.

Answer 1

使用一点技巧，我在基本 HTML 上实现了您想要的布局。

我更改了关键项目的颜色，以便更容易跟踪它们

.grid {
  width: 200px;
  display: grid;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-auto-rows: 50px;
  grid-column-gap: 5px;
  grid-row-gap: 5px;
  grid-auto-flow: dense;
  transform: rotateY(180deg);
}

.cell {
  background: tomato;
  width: 100%;
  height: 100%;
  transform: rotateY(180deg);
}

.cell:nth-child(10n + 1) {
  background: lightgreen;
  grid-column: span 2;
  grid-row: span 2;

}

.cell:nth-child(10n + 10) {
  background: lightblue;
  grid-column: span 2;
  grid-row: span 2;

}

.cell:nth-child(10n + 8) {
  background: yellowgreen;
  grid-column: 1;
}

.cell:nth-child(10n + 9) {
  background: yellow;
  grid-column: 2;
}

<div class="grid">
  <div class="cell">1</div>
  <div class="cell">2</div>
  <div class="cell">3</div>
  <div class="cell">4</div>
  <div class="cell">5</div>
  <div class="cell">6</div>
  <div class="cell">7</div>
  <div class="cell">8</div>
  <div class="cell">9</div>
  <div class="cell">10</div>
  <div class="cell">11</div>
  <div class="cell">12</div>
  <div class="cell">13</div>
  <div class="cell">14</div>
  <div class="cell">15</div>
  <div class="cell">16</div>
  <div class="cell">17</div>
  <div class="cell">18</div>
  <div class="cell">19</div>
  <div class="cell">20</div>
  <div class="cell">21</div>
  <div class="cell">22</div>
  <div class="cell">23</div>
</div>

现在，相同的布局没有技巧（但使用更多规则）

.grid {
  width: 200px;
  display: grid;
  grid-template-columns: 1fr 1fr 1fr 1fr;
  grid-auto-rows: 50px;
  grid-column-gap: 5px;
  grid-row-gap: 5px;
  grid-auto-flow: dense;
}

.cell {
  background: tomato;
  width: 100%;
  height: 100%;
}

.cell:nth-child(10n + 1) {
  background: lightgreen;
  grid-column: 3 / 5;  /* strange behaviour */
  grid-row: span 2;
}

.cell:nth-child(10n + 2),
.cell:nth-child(10n + 4) {
  background: papayawhip;
  grid-column: 2;

}

.cell:nth-child(10n + 6),
.cell:nth-child(10n + 8) {
  background: yellowgreen;
  grid-column: 4;
}

.cell:nth-child(10n + 7),
.cell:nth-child(10n + 9) {
  background: yellow;
  grid-column: 3;
}

.cell:nth-child(10n + 10) {
  background: lightblue;
  grid-column: 1 / 3;    /* strange behaviour */
  grid-row: span 2;

}

<div class="grid">
  <div class="cell">1</div>
  <div class="cell">2</div>
  <div class="cell">3</div>
  <div class="cell">4</div>
  <div class="cell">5</div>
  <div class="cell">6</div>
  <div class="cell">7</div>
  <div class="cell">8</div>
  <div class="cell">9</div>
  <div class="cell">10</div>
  <div class="cell">11</div>
  <div class="cell">12</div>
  <div class="cell">13</div>
  <div class="cell">14</div>
  <div class="cell">15</div>
  <div class="cell">16</div>
  <div class="cell">17</div>
  <div class="cell">18</div>
  <div class="cell">19</div>
  <div class="cell">20</div>
  <div class="cell">21</div>
  <div class="cell">22</div>
  <div class="cell">23</div>
