Centre Align Menu

Hey, I want to centre my menu, however I am not sure how to do this. I’m pretty sure I need to edit the following code, I’m just not sure which part to edit and what to edit it to.

/* * 4.1 home header */
.home-header {
	background:#fff;
	min-height:0px;
	width:100%;
	/*top:0;
	*/
	z-index:100;
	padding:0;
	margin:0;
}
.home-logo {
	float:left;
	margin-top:0px;
	margin-left:0px;
}
.home-navbar {
	float:right;
	margin-top:20px;
	margin-right:20px;
	width:50px;
	height:34px;
	display:none;
	background:url(images/navbar.png) no-repeat;
}
.home-navigation {
	float:centre;
	height:100%;
	margin-left:450px;
	margin-right:100px;
}
.home-navigation ul {
	display:inline-block;
}
.home-navigation li {
	float:left;
	list-style-type:none;
}
.home-navigation > ul > li > a > span {
	padding:10px;
	border-radius:0px;
}

.home-navigation li a {
	/*color:#fff;*/
	font-size:20px;
	text-transform:;
	display:block;
	padding:0 15px;
	line-height:70px;

.home-container {
	width:1120px;
	overflow:hidden;
	margin:0 auto;
	padding:00px 5%;
	text-align:center;
	font-size:16px;
	color:#666;
	z-index:98;
	max-width:100%;
	/* position: absolute;*/
}

Any help would be really appreciated!

Thank you 🙂
