可以利用input标签与lable标签组合实现banner图的切换。
<label> 标签为 input 元素定义标签（label）。
label 元素不会向用户呈现任何特殊的样式。不过，它为鼠标用户改善了可用性，因为如果用户点击 label 元素内的文本，则会切换到控件本身。
<label> 标签的 for 属性应该等于相关元素的 id 元素，以便将它们捆绑起来。
input标签有个checked属性，当lable属性绑定后，选中lable即可选中input标签。

隐藏input，因为这里我们只需用到input的checked属性。选中lable时，与之绑定的Input也会处于checked状态，这样，我们只需利用checked属性加上伪类选择器。就可以实现banner图的切换。由于定位的原因，会使后面的图盖住前面的图，所以需要设置z-index使图片上去.

但是好像用这种方法，能点击，就不能自动轮播了。

效果图如下：（祖传的天仙照片都贡献出来了）
demo代码如下：
<!DOCTYPE html>

display: inline-block;
opacity: 0.3;
height: 70px;
width: 70px;
margin-top: 100px;
background-color: red;
}
label:hover{
opacity: 1;
}
input{
display:none;
}
ul{
list-style: none;
padding: 0px;
height: 499px;
width: 375px;
overflow: hidden;
margin-left: 480px;
position: relative;
}
img {
width: 100%;
}
.set_page1:checked ~.photo ul li:nth-child(1){
position: absolute;
top: 0px;
z-index: 25;
}
.set_page2:checked ~.photo ul li:nth-child(2){
position: absolute;
top: 0;
z-index: 22;
}
.set_page3:checked ~.photo ul li:nth-child(3){
position: absolute;
top: 0;
z-index: 23;
}
.set_page4:checked ~.photo ul li:nth-child(4){
position: absolute;
top: 0;
z-index: 24;
}

.set_page5:checked ~.photo ul li:nth-child(5){
