Align background image middle and center

Question

Here\'s the html:

Answer 1

Use a simple JQuery fn called center ( Usage: $(element).center() ):

     jQuery.fn.center = function() {
        this.css("position","absolute");
        this.css("top", (($(window).height() - this.outerHeight()) / 2) + $(window).scrollTop() + "px");
        this.css("left", (($(window).width() - this.outerWidth()) / 2) + $(window).scrollLeft() + "px");
        this.css("bottom", (($(window).width() - this.outerWidth()) / 2) + $(window).scrollLeft() + "px");
        return this;
      }
    $(document).ready(function(){
$(#imgUtility).center();
)};

With the HTML:

 
   
    "  />
