我正在尝试创建一个响应式网站，但是我被困在一个地方，即带有背景图像蒙版的图像无法正常运行。它在较大的屏幕上可以正常工作，但在中型和小型屏幕上，我的标题和某些图像在“蒙版”背景图像下看不到。那你能告诉我我在哪里犯错吗？是编码还是我做错的方法？
如何显示屏幕的图片在此页面的底部。您可以在大屏幕上看到没有问题，但是在其他屏幕上您看不到标题，并且只显示一半的图像，并且背景没有伸展覆盖所有图像和标题！！！
enter link description here这是网站。您可以更好地了解问题所在。

您可以在较小的屏幕上使用媒体查询。在手机上尝试以下CSS：
header{
height: auto;
}
#intro{
padding: 0;
height: auto;
}
.full-bg-img{
position: relative;
}
