Question

我正在尝试在导航栏后面放置一个图像，并使导航栏位于图像的下部。我尝试将位置数据添加到.navbar，但不会将其向下移动。此外，导航栏下方图像的下半部分也被切除。如果我在图像上添加高度信息，则会显示完整图像，但在响应模式下，导航菜单和主页会重叠。我尝试将图像作为.bg-light的背景，并作为导航栏中的html中的图像。

我是Bootstrap的新手（我真的很喜欢它），感谢您的帮助。

.bg-light{
	background-image:url("http://www.peterrussell.com/images/header2.jpg")!important; 
	background-repeat: no-repeat; 
}
