<style>

*/
#colorbox, #cboxOverlay, #cboxWrapper{position:absolute; top:0; left:0; z-index:9999; overflow:hidden;}
#cboxOverlay{position:fixed; width:100%; height:100%;}
#cboxMiddleLeft, #cboxBottomLeft{clear:left;}
#cboxContent{position:relative;}
#cboxLoadedContent{overflow:auto;}
#cboxTitle{margin:0;}
#cboxLoadingOverlay, #cboxLoadingGraphic{position:absolute; top:0; left:0; width:100%;}

.cboxPhoto{float:left; margin:auto; border:0; display:block;}
.cboxIframe{width:100%; height:100%; display:block; border:0;}
/*
