Moving my Supersized Slideshow

* { margin:0; padding:0; }
body { background:#111; height:100%; }
	img { border:none; }

	#supersized-loader { position:absolute; top:50%; left:50%; z-index:0; width:60px; height:60px; margin:-30px 0 0 -30px; text-indent:-999em; background:url(../img/progress.gif) no-repeat center center;}

	#supersized {  display:block; position:absolute; left:0; top:0; overflow:hidden; z-index:-999; height:100%; width:100%; }
		#supersized img { width:auto; height:auto; position:absolute; display:none; outline:none; border:none; }
			#supersized.speed img { -ms-interpolation-mode:nearest-neighbor; image-rendering: -moz-crisp-edges; }	/*Speed*/
			#supersized.quality img { -ms-interpolation-mode:bicubic; image-rendering: optimizeQuality; }			/*Quality*/

		#supersized li { display:block; list-style:none; z-index:-30; position:fixed; overflow:hidden; top:0; left:0; width:100%; height:100%; background:#111; }
		#supersized a { width:100%; height:100%; display:block; }
			#supersized li.prevslide { z-index:-20; }
			#supersized li.activeslide { z-index:-10; }
			#supersized li.image-loading { background:#111 url(../img/progress.gif) no-repeat center center; width:100%; height:100%; }
				#supersized li.image-loading img{ visibility:hidden; }
			#supersized li.prevslide img, #supersized li.activeslide img{ display:inline; }

this is the code in the supersized.css file. there’s other files associated with the slideshow too that i can show you if need be but i just have a feeling that this is where something needs to be changed. i just want this slideshow to be moved over to the right a little. i’d like to trial & error it by the pixels (50, 100, 150, etc until i get it perfect). nothing i do seems to move the slideshow.

any ideas what i’m doing wrong.

thank you!
