我的 css 幻灯片不工作

Question

我目前正在学习 CSS。我正在尝试制作图像滑块，但无法正常工作。我不知道我的代码有什么问题。

当我 select 第 2、3、4 个按钮时，图像没有改变。我不知道我的代码有什么问题。

删除

.image-in-slider,

来自

.container input.radio-image-1:checked ~ .image-in-slider,
.image-in-slider .img1 {
    background-image: url(http://s23.postimg.org/kvzwiar2z/image1.jpg);
}

并将结尾的“/”添加到输入元素中。 http://jsfiddle.net/LusL3s99/5/
