当我向图像添加超链接并开始调整页面大小时，空的col-2 cloumn会越过图像的第一列。如果我删除超链接，一切正常。为什么会发生这种情况，我该如何解决？

Answer 1

在下面，您可以找到3种情况：

作为您随附的代码笔中的代码
如果您从徽标周围删除<a>
如果您使用col-4

第3个选项应该对您有用，如果没有，请与您分享所需的内容

.vertical-align {
  display: flex;
  align-items: center;
}

      <h4>this is when you have col-4 instead of empty col-2</h4>
    </div>
  </div>

</div>

引导程序：调整页面大小时，标头中的第二个col-2优先于第一个col-2
