Can someone simplify my css code

[tobes]

Basically my css code is really long winded and is not always working in ie.

Thanks in advanced.

#navigation {
	height: 50px;
	background: #303136;
}

#navigation ul {
	margin: 0px;
	padding: 0 0 0 20px;
	list-style: none;
}

#navigation li {
	display: inline;
}

#navigation a {
	display: block;
	float: left;
	border: none;
	background: no-repeat left 55%;
	padding: 14px 36px 10px 30px;
	text-decoration: none;
	color: #FFFFFF;
}

#navigation a:hover {
	color: #FFF;
	background:#1776b8 url(../images/navigation_arrow.gif) no-repeat right;
}

#navigation-link {
	float:left;
	height:30px;
	color:#FFFFFF;
	font-weight:bold;
	font-size:13px;
}

#navigation-link a {
	color:#FFFFFF;
	text-decoration:none;
	display:block;
	height:100%;
}
