我已经查看了几个有关此事的问题;但是,他们似乎都没有解决或解决这个问题。
实质上发生的是h1和nav元素并排结束但没有正确排列。我已尝试过多个显示和浮动设置,但都没有。
CSS本身相对干净,也许flex不能正常工作或者我没有正确使用它?我不确定在这里引起问题的是什么帮助非常感谢!

删除h1元素允许我正确地将填充添加到nav元素的顶部。虽然,两者都只允许我正确填充h1。我确定填充不是垂直居中的最佳方式,但问题仍然存在。
更新:
我快速标记了截图,希望能够澄清问题。底部的红线显示了当前文本的排列方式。虽然顶部的红线表明li元素应该如何垂直居中。
由于这表明可能更大的问题是它目前如何设置为元素不要&#34;快速&#34;如果你愿意的话。

display: inline-block;
元素可以使用vertical-align: middle;
垂直居中对齐,只需将其添加到h1
和nav
