El CSS del slider:

Código HTML:

/* These are just the demo styles and these can be removed and Orbit 
will still work like a champ (except any content block needs a background which
our demo gets from this sheet) */

.container {
    position: relative; 
    left:4.5%;
	}
    
.content { background: url(dummy-images/coffee.jpg); }
.content h1 {
	font-size: 40px; 
	text-transform: uppercase; 
	font-weight: bold; 
	text-align: center;
	margin-top: 180px;
	color: #222;
	line-height: 50px;  }
.content h3 {
	text-align: center; 
	font-size: 22px; 
	color: #222; }
