Question

​

.hero__grid {
  display: grid;
  grid-template-columns: 1fr auto 1fr;
  grid-template-rows: 1fr auto 1fr;
}

.vertical-line {
  height: 169px;
  width: 0.5px;
  background-color: red;
}

.horizontal-line {
  width: 300px;
  height: 0.5px;
  background-color: red;
}

<div class="hero__grid">
  <div class="hero__grid-cell"></div>
  <div class="hero__grid-cell">
    <div class="vertical-line"></div>
  </div>
  <div class="hero__grid-cell"></div>
  <div class="hero__grid-cell">
    <div class="horizontal-line"></div>
  </div>
  <div class="hero__grid-cell"><i class="far fa-heart"></i></div>
  <div class="hero__grid-cell">
    <div class="horizontal-line"></div>
  </div>
  <div class="hero__grid-cell"></div>
  <div class="hero__grid-cell">
    <div class="vertical-line"></div>
  </div>
  <div class="hero__grid-cell"></div>
</div>

我试着做到这一点：

​

一开始我只是想：

display: grid;
grid-template-columns: 1fr 1fr;
grid-template-rows: 1fr 1fr;

并以某种方式将这些线条和图标放置在那里，但它似乎最终无法工作。我想做的是制作一个网格3x3，这样就可以：

grid-template-columns: 1fr auto 1fr;
grid-template-rows: 1fr auto 1fr;

在auto (第二行和第二列)中，div只是把这些内容放在一起，但在我看来不太对。我知道CSS不是十全十美的，所以也许它实际上是处理它的最好方法？

1. 如何使网格单元格之间的边框(或仅仅是行)产生这样的效果？ 我试过border-bottom，但它的宽度/高度都很高。
2. 如何将心脏图标放在边境线中央的中间？

Answer 1

此方法对行和列之间的沟槽使用grid-gap。

心脏图标是绝对安放和变身向上和留下一半的大小。

gap (网格-间隙) gap CSS属性设置行和列之间的间隙(沟槽)。它是行隙和列隙的缩写.
