引导样式干扰 CSS 中的网格框答案

【问题标题】：bootstrap styles interfering with grid-box in css引导样式干扰 CSS 中的网格框
【发布时间】：2020-10-04 00:19:22
【问题描述】：

我想做一个网格，但是第一个元素（img）没有出现在第一个位置，而是出现在第二个位置。第一个图像点留空。我检查了造成这种情况的原因，似乎引导链接 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css"> 中的样式无法让我的网格框正常工作，如果我删除它，我的导航栏将无法正常工作。

在此处查看代码：Jsfiddle link

请提出修复建议。任何帮助将不胜感激。谢谢。

【解决方案1】：

因为 bootstrap 3 使用 float ，它也使用伪元素来清除浮动。

这里一个伪.container:before{display:table;content:" "} 填满了第一个单元格，重置顺序以将其放在最后。 https://jsfiddle.net/nhak72r1/

/* fix update */

.container::before {
  display: none;  /* hide it */
  order: 1;  /* set it last , if you already use order for other element, set the highest value for it */
}


/* end update */

* {
  box-sizing: border-box;
}

.container {
  display: grid;
  grid-template-rows: repeat(4, auto);
  grid-template-columns: repeat(4, auto);
  grid-gap: 5px;
  align-items: center;
}

.container>img {
  width: 100%;
  border-radius: 20px;
}

.container>img:nth-child(6) {
  grid-row: span 2;
  grid-column: span 2;
  width: 100%;
}
