我不明白为什么body元素不包含页脚，这与我在代码中定义的方式不同 如果div.container的高度是其父级/顶级div的50%，则将其位置设置为绝对位置并进行设置
.parent-of-container{
position:relative;
}
.container{
position:absolute;
top:25%;
....
}
请尝试以下代码。希望它能帮助你。只需根据您的要求设置
高度边距位置 container{
height: 87%;
margin-top: -10%;
position: fixed;
top: 50%;
}
container{
height: 87%;
margin-top: -10%;
position: fixed;
top: 50%;
}
