css使背景图像位置固定并滚动内容

Question

我们怎么能做类似于这个例子中所做的事情http://theme.nileforest.com/html/mazel-v1.1/home-text-rotator1.html

他们正在修复背景图像和内容.我不确定他们是如何做到这一点只有css或他们使用java脚本.

我仍然想弄明白.

任何固定的示例或指针都可以很好地开始

Answer 2

尝试添加

#myBackgroundContainer{
    background-attachment:fixed;
}

来自文档

background-attachment CSS属性确定图像的位置是否在视口中固定,或者与其包含的块一起滚动.

body  {
    background-image: url('https://encrypted-tbn3.gstatic.com/images?q=tbn:ANd9GcSHC-qntWkhfC_CP9UcIle2WQItuhlbFS_AGK3WdtrAc4Pp6OIu');
    background-repeat: no-repeat;
    background-attachment: fixed;
}
#Partition{
  background:gray;
  height:200px;  
}
