Hi please take a look at my site, below is the code snippet in question i have to center my images since ive never had any luck with the css-html methods. The problem is because its set to wait for document.ready() sometimes it will place all my images to the right. Ive tried window.load() but the images center offscreen at smaller window sizes. It was also suggested i try

<div style="
  background: url('Assets/image.png') center center no-repeat;
  width: 100%;
  height: 500px;
 ">
 </div>

but this causes it to lose responsiveness. Ive searched around and i cant find a solution, i just need my images (and the one form) to stay centered and for the images to scale down with the window size.

site:

<script type="text/javascript"> //Centering Script


$(document).ready(function () {
    updateContainer();
    $(window).resize(function() {
        updateContainer();
    });
});


function updateContainer() {


(function ($) {
$.fn.vAlign = function() {
    return this.each(function(i){
    var h = $(this).height();
    var oh = $(this).outerHeight();
    var mt = (h + (oh - h)) / 2;    
    $(this).css("margin-top", "-" + mt + "px"); 
    $(this).css("top", "50%");
    $(this).css("position", "absolute");    
    }); 
};
})(jQuery);

(function ($) {
$.fn.hAlign = function() {
    return this.each(function(i){
    var w = $(this).width();
    var ow = $(this).outerWidth();  
    var ml = (w + (ow - w)) / 2;    
    $(this).css("margin-left", "-" + ml + "px");
    $(this).css("left", "50%");
    $(this).css("position", "absolute");
    });
};
})(jQuery);

Remove that whole script. Place this in your CSS.

img{
    display: block;
    margin: 0 auto;
}

just do

<style>
a{
display:block;
text-align:center;
}

</style>



<a href="Assets/OrderSheet.xls">
    <img src="Assets/OrderSheet.png" class="image">
</a>

no need for repositioning

No need for js, CSS alone is fine. Set your image to display block, set a width and Max width plus margin auto.

img {
display: block;
width: 300px;
max-width: 100%;
margin: 0 auto;
}

If you won't accept the method suggested by others, I would suggest using em's. Best to use them everywhere, but you could just apply them to your images.

Then use media queries to scale up/down all elements with values specified in em's, by changing the base font-size for different screen sizes.

center a responsive sized element

/* element/id/class */ 
/* margin is 100 - width / 2 */

img {
width:34%;    
margin: 0 33%;
}
