我可以在ans方面帮助您，但代码太多，无法理解。只要用一个问题画一个JSFIDLE，我就可以看到问题的确切位置，并找到相应的解决方案。我感谢你的帮助。我看到了你的小提琴，基于背景图像没有响应的问题，我让我的JSFIDLE解决了这个问题。看看它，告诉我它的输出是否正确。我试过了，但没用。我认为这与我如何设置媒体查询断点有关，因为当我将浏览器从最小宽度1200px（桌面）扩展到320px（移动）时，我失去了高度。这是我的媒体查询设置。您的媒体查询代码太乱，无法理解。我想你没有检查我在小提琴中使用的外部资源。我根本没有使用媒体查询，它仍然是响应性的。我有我在JSFIDLE上写的完整代码，所有的外部文件都是CDN，所以如果你想要这些代码，那么只需评论一下你的电子邮件id，我就会把你的代码发出去。
