导航栏下方的新内容会在结束标记之后在导航栏内结束

Question

对于新网站的首页，我对导航栏，徽标和背景图片感到满意。我的问题是，当我尝试在关闭nav标签之后添加新的div，部分或图像时，新内容被插入到导航栏中。我不知道为什么用导航栏将新的内容区域放入其中。

我的目标是在主页的中心放置一些内容（例如：图像，H1 /文本等）。

我尝试在关闭的nav和div标签下面添加新的div，部分和/或图像。从那里我尝试为新内容设置样式，但是由于某种原因，我无法使内容移到正确的位置。

Answer 1

我已删除logo和nav-wrapper的浮动元素，以避免与另一个div重叠。我已经使用flex-box来对齐徽标和菜单。

并调整了媒体查询的响应速度。希望该解决方案对您有所帮助。
