祝你有个美好的一天!我知道这是一个常见问题，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 View 在较小的设备中时背景图像被裁剪。

我已经尝试将 html 和正文设置为 100%，但无济于事。我试过将背景大小设置为 100% 100% 无济于事。我试过这个链接 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:

最佳答案

尝试使用 min-height 这样它就不会从背景图像的底部裁剪。检查下面给出的示例代码。我在 body css 标签中给出了 min-height:745px。

body {
    background-image: url(https://images.pexels.com/photos/236047/pexels-photo-236047.jpeg);
    background-size: cover;
    background-position: center;
    background-repeat: no-repeat;
    font-family: Josefin Sans Regular;
    color: white;
    min-height: 725px;
}

html {
    height: 100%;
}

                 0px 18px 23px rgba(0,0,0,0.1);
    padding-top: 25%;
