This should be quite easy, and I have done some research on this. I have spliced code from here, here, here, and other places, but I can’t get this to work.

I have a webpage which has 3 .pngs layered on top of each other. The top two are variable sized, and 100% of the page. The top one has a hole in it (it’s transparent in the middle), and the middle disappears using Javascript to reveal the bottom one. The top two .pngs and the Javascript are working perfectly.

I want the bottom image to be in the exact center, vertically and horizontally, and be proportional to the page size. I can get it centered, or proportional, but not both. I can’t put the bottom picture as the background, because then the background isn’t the right color, or it’s tiled.

Here is a sample of some of the code:

HTML:

<body>  
        <div >
    <p0 id="face" ><img src="face2.png"; class='face'> </p0>
</div>
        <p1 id="circuit" > <img src= 'circuit.png' width = '100%' height = '100%' /> </p1>
        <p2 id="hole" ><img src="hole.png" width='100%' height = '100%' /> </p2>
</body>

CSS:

p0{ 
width: 50%;/*I can't set the height to 50% because it is a different size than the width*/
center
z-index:1;
position: absolute; 
}

p1{
z-index: 2;
width: 100%;
padding:0;
margin: 0;
height:100%;
position: absolute; 
}

p2{
z-index:3;
width: 100%;
padding:0;
margin: 0;
height:100%;
position: absolute; 
}

    put everything that you want centered into a div that has these:

       .div{
     width: 100%;
     position: relative; // or absolute
     text-align: center;
     text-align: -moz-center;
     text-align: -webkit-center;
     }

    here is a linkjsfiddle

    here is full CSS: both images are different sizes in the exact center on top of each other as the question stated,

    .parent{
 width: 100%;
 position:  absolute;
 text-aligh: -align: center;
 text-align: -moz-center;
 text-align: -webkit-center;

 }

.center1{

height:120px;
width: 275px;    
background-image: url("http://www.google.com/images/srpr/logo3w.png");
}

.center2{       
height: 100px;
width: 200px;
 background-image: url("http://www.google.com/logos/2012/turing-doodle-static.jpg");
}

    ​
    HTML:

         <div class="parent" style="z-index: 1;">
         <div class="center1"></div> 
     </div>
     <div class="parent" style="z-index: 10;">
         <div class="center2"></div> 
     </div>
