这是我有史以来的第一篇文章。我对编码还很陌生，这就是到目前为止我得到的标头。
问题是，根本没有显示汉堡菜单按钮，并且ul的一部分最终出现在我的徽标图像之下。
我已经尝试了两天以找出问题所在，但对于大多数初学者来说，我自己就可以找到解决方案。
如果我发布此代码错误，请原谅我（我不知道为什么代码是无色的）

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

滚动和调整视图端口的大小有些不同，但是我将JSFiddle放在了here处。
几位：
在使用引导程序以及尝试执行的操作时，可以使它们更接近于它们的标准。我刚刚为此调整了html。
但是，我添加了一些CSS来覆盖background: transparent样式，以将您的按钮设为边框并产生“汉堡”，
我不得不添加一些jQuery，因为onClick搞砸了。不知道为什么。
它并不完美，但我希望它能对您有所帮助。要使导航消失并显示按钮，请水平缩小屏幕。
