为什么使用网格模板区域显示网格不起作用？

Question

我试图通过网格模板区域实现元素排列，但它不起作用。我正在尝试使用网格系统垂直和水平排列块。使用左侧的图片和另一侧的文字。为什么这段代码不起作用？

.news__wrapper {
  display: grid;
  grid-template-areas: "a a c" "b b c";
}

.news__item {
  display: flex;
  align-items: center;
  justify-content: center;
}

.news__item-image {
  width: 349px;
  height: 360px;
}

.news__item-image {
  background: "url(https://place-hold.it/300x500) 50% 50% no-repeat";
}

<div class="news__wrapper">
  <div class="news__item">
    <div class="news__item-image"></div>
    <div class="news__item-content">
      <h4 class="news__item-title">
        Lorem,
      </h4>
      <p class="news__item-text">
        Lorem ipsum
      </p>
    </div>
  </div>
  <div class="news__item">
    <div class="news__item-image" :style="imageNews1"></div>
    <div class="news__item-content">
      <h4 class="news__item-title">
        Lorem,
      </h4>
      <p class="news__item-text">
        Lorem
      </p>
    </div>
  </div>
  <div class="news__item">
    <div class="news__item-image" :style="imageNews1"></div>
    <div class="news__item-content">
      <h4 class="news__item-title">
        Lorem,
      </h4>
      <p class="news__item-text">
        Lorem ips
      </p>
    </div>
  </div>
</div>

Answer 1

当您使用grid-template-areas时，您需要将grid-area值分配给网格内的元素。
简而言之，添加以下 css 代码将达到预期的结果：

.news__item:first-child {
  grid-area: a;
}
.news__item:nth-child(2) {
  grid-area: b;
}
.news__item:nth-child(3) {
  grid-area: c;
}
