我做了一个网站，它是移动响应的，有一个粘性的标题。但在Iphones上，汉堡按钮不在正确的位置，而且也不能完美地与粘性的头部一起移动。我不知道这是因为Safari，然而，我在其他工具上没有遇到这个问题，只有在iPhone上。如果我在一个地方更改汉堡按钮的位置，它在另一部手机上看起来就不太好了。
我不使用Bootstrap。我的问题是，我如何才能让我的汉堡按钮在每个手机上都好看？

</header>第一种方法
将align-items: center;添加到nav标记中。那就是
nav{align-items: center;}
同时移除汉堡包类中的top:20%;。那是
.hamburger{top:20%}
位置：固定了元素，该元素至少分配了顶部、左侧、底部和右侧中的一个。
所以，这里是正确的：5%只够了。
