html - Bootstrap 网格 3x3 Firefox 与 Chrome 错误

Question

我有以下标记:

.myclass {
  display: flex;
  flex-wrap: wrap;
}
.myclass img {
  width: 100%;
  display: block;
  height: auto;
}

就您所见，它是 3x3 Bootstrap 网格。但它表现得非常奇怪:在我的 Firefox 中，我只有 .myclass 的一切都是正确的。 但是如果没有这条线，我有 3 个正确的列，而不是 2 个清晰的列，然后每行有 1 列。通过这一行，我在 Chrome 中遇到了错误:有 2 个正确的列和清晰的位置而不是第三列。我该如何解决这个问题？

在 bootstrap 中，你不应该溢出一行宽度总和大于 12 的列。这意味着你想要在布局中构建的每一行都应该在单独的 <div class="row"></div> 中。 .检查下面的代码片段是否解决了您的问题。

.myclass img {
  width: 100%;
  display: block;
  height: auto;
}
