将图片悬停在其他内容下方

Question

i'm trying to add some hover selector for the images of the page i'm currently developing, but as i point the cursor on the image, hover works fine but the position was somehow wrong because it appears under the content close to it. i've tried using z-index and positions. and one more thing, i also want it to zoom from the center of the div, and from the corner . any help?check out this fiddle

  CSS:
  html, body { 
  margin: 0; 
   height: 100%; 
   }

.management_wrapper{
 text-align: center;
 max-width: 80%; ;
 height:auto;
 background-color: white;
 padding-top: 0%;
 padding-bottom: 10%;
 position: relative;
 overflow: auto;
 margin-left: 5%; 
 }

#list_box{
margin-top: 1%;
width: 15%;
height:20%;
float:left;
background-color:beige;
margin-right:1%;
position: relative;
}
#info{

height:20%;
float:left;
color: white;
margin-right: 1%;
position: relative; 
}
#info p{
margin-top: 20%;
