由 dawei 这篇文章主要给大家分享css盒子的隐藏和显示效果的实现，需求就是常规就是隐藏效果，显示的时候显示在最上层，例如下面小米电视机这种选购效果，那么这样的隐藏和显示效果怎样做呢？我们直接来看代码：
.imgbox{
width: 1200px;
height: 612px;
margin-right: auto;
margin-left: auto;
margin-top: 60px;
}
.m1{
border: solid;
border-width: 1px;
height: 300px;
width: 227px;
}
#m1img{
text-align:center;
padding-top: 55px;
}
#img2{
margin-bottom: 35px;
}
p>span {
text-decoration:line-through;
}
#where1{
position: absolute;
left:412px;
top: 60px;
}
#where2{
position: absolute;
left:651px;
top: 60px;
}
#where3{
position: absolute;
left:890px;
top: 60px;
}
#where4{
position: absolute;
left:1129px;
top: 60px;
}
#where5{
position: absolute;
left:412px;
top: 372px;
}
#where6{
position: absolute;
left:651px;
top: 372px;
}
#where7{
position: absolute;
left:890px;
top: 372px;
}
#where8{
position: absolute;
left:1129px;
top: 372px;
}
#sbox{
height:76px;
width: 227px;
background-color: #ff6700;
opacity: 0;/*隐身*/
z-index:999;
position: absolute;
bottom: -0.5px;
}
#where1:hover #sbox{
opacity: 1;
}
#where2:hover #sbox{
opacity: 1; (显示)
}
#where3:hover #sbox{
opacity: 1;
}
#where4:hover #sbox{
opacity: 1;
}
#where5:hover #sbox{
opacity: 1;
}
#where6:hover #sbox{
opacity: 1;
}
#where7:hover #sbox{
opacity: 1;
}
#where8:hover #sbox{
opacity: 1;
}
#sboxp{
line-height: 76px;
