I think its not the case to use img-responsivehere, since it was for <img />
我认为img-responsive这里不是这样使用的，因为它是为了<img />
and for making the divbackground image responsive, we can use background-size: cover;
为了使div背景图像具有响应性，我们可以使用background-size: cover;
background-size: cover;
Scale the image, while preserving its intrinsic aspect ratio (if any), to the smallest size such that both its width and its height can completely cover the background positioning area
背景尺寸：封面；
将图像缩放到最小尺寸，同时保留其固有纵横比（如果有），使其宽度和高度都可以完全覆盖背景定位区域

To make background-image responsive, you can use background-size: coverCSS property. or if you want to stretch the background-image with resize in the div, use background-size: 100% 100%.
要使背景图像响应，您可以使用background-size: coverCSS 属性。或者，如果您想在 div 中使用调整大小来拉伸背景图像，请使用background-size: 100% 100%.
