Bootstrap 带有图片的粘性页脚

Question

我想要实现的是一个带有粘性页脚的页面，这是一个矢量岛。

小岛总是在页面的底部，但是当浏览器高度太小时它会调用垂直滚动。
岛的后面是朝阳，然后落在所有页面内容的后面。这是相当大的，大约 1417px 高。不过这不会影响垂直滚动。

这是我目前的情况，我已经被困了几个小时了！任何帮助将不胜感激。

Answer 1

最好用css中的图片作为背景图片:

见https://jsfiddle.net/6t9vxq1o/1/

.body{
    height:100%;
    background: url(http://i.imgur.com/wSNrfJD.png) no-repeat center bottom;   
}
#wrap{
    background:url(http://i.imgur.com/alDv0tE.png) no-repeat center bottom;   
}

这样图像将始终在底部，阳光在内容后面，草在页脚后面
