将 2 个不同的 div 悬停在第三个不同的 div 上

My page has 3 divs that are located horizontally. I need to make the 2 divs move to the sides of the page (left div move to left, and right div move to right) when the center div is on hover. I can make the left div move, but the right div isn't moving. I hope to get this achieved using CSS, if not please advise. Thanks a lot.

我的代码如下:

.container 
   {
    position:absolute; bottom:0; right:0; left:0;
    margin-right:auto; margin-left:auto;
    width:50%; height:10%;
   }
.a {position:absolute; bottom:0; left:20px; width:30%;}
.b 
   {
    position:absolute; bottom:0; right:0; left:0;
    margin-right:auto; margin-left:auto; width:30%;
   }
.c {position:absolute; bottom:0; right:20px; width:30%;}

.b:hover + .a{
-moz-transform:translatex(-50px);
-ms-transform:translatex(-50px);
-o-transform:translatex(-50px);
-webkit-transform:translatex(-50px);
transform:translatex(-50px);
}

.b:hover + .c{
-moz-transform:translatex(50px);
-ms-transform:translatex(50px);
-o-transform:translatex(50px);
-webkit-transform:translatex(50px);
transform:translatex(50px);
}

<div class="container">
    <div class="b">Div b</div>
    <div class="a">Div a</div>
    <div class="c">Div c</div>
</div>

将选择器从 + 改为 ~:
