【问题描述】：
祝你有美好的一天！ 我知道这是一个常见问题，并且已经解决了很多次，但实际上我已经尝试了搜索引擎和 stackoverflow 返回给我的所有搜索解决方案，但我真的无法解决这个问题。
问题是当视图在较小的设备中时背景图像被裁剪。
我尝试将 html 和 body 设置为 100% 无济于事。 我尝试将背景大小设置为 100% 100% 无济于事。 我已经尝试了这个链接CSS: Full Size background image，但仍然无济于事。
这是css代码：
body {
background-image: url(../img/bg2.jpg);
background-size: cover;
background-position: center;
background-repeat: no-repeat;
font-family: Josefin Sans Regular;
color: white;
}
html {
height: 100%;
}
#content {
text-align: center;
text-shadow: 0px 4px 3px rgba(0,0,0,1),
0px 8px 13px rgba(0,0,0,0.1),
0px 18px 23px rgba(0,0,0,0.1);
padding-top: 25%;
}
#carHead {
text-align: center;
}
h1 {
font-weight: 700;
font-size: 5em;
}
hr {
width: 45%;
background-color: #f8f8f8;
border-top: 1px solid #f8f8f8;
border-bottom: 1px solid rgb(0,0,0.02)
}
.carousel-item {
padding: 20px;
}
这是 html 代码的主体：
