导航栏的背景图像不适合

Question

我的导航栏顶部和底部有70px的填充。高度明智，这是一个比平时更大的导航栏。我正在尝试使用照片将整个空间填充为导航栏的背景，但它只填充中间的一个非常小的空间，导航栏的其余部分保持白色。如何用我的照片填充导航栏的整个空间？

.navbar {
	text-transform: uppercase;
	margin-bottom: 0px;
}

.navbar-inner{
  background-image: url('../img/mixer.jpg');
  background-repeat: repeat-x;
}

.navbar-default {
	padding-top: 70px;
	padding-bottom: 70px;
	border-color: #1E1E20; /*light black*/
}

.navbar-brand {
	font-weight: 700;
	font-size: 20px;
	letter-spacing: 2px;
}

ul.nav a { 
	color: #1abc9c !important; /*teal*/
}

ul.nav a:hover,
ul.nav a:focus { 
	color: #7b7b7b !important; /*lightest grey*/ 
} 

.navbar-default .navbar-toggle {
	border-color: transparent;
}

<div class="navbar navbar-default navbar-static-top" role="navigation">
			<div class="navbar-inner">
			  <div class="container">
				  <div class="navbar-header">
					  <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
						  <span class="icon-bar"></span>
						  <span class="icon-bar"></span>
						  <span class="icon-bar"></span>
					  </button>
					  <a href="index.html" class="navbar-brand">KEN COOPER</a>
				  </div>

				  <div class="collapse navbar-collapse">
					  <ul class="nav navbar-nav navbar-right">
						  <li><a href="#">About</a></li>
						  <li><a href="#">Shows</a></li>
						  <li><a href="#">Clients</a></li>
						  <li><a href="#">Contact</a></li>
					  </ul>
				  </div> <!-- end navar collapse -->
			  </div>
			</div>
		</div>
