html - CSS 渐变导航设计

Question

我正在尝试创建一个导航栏，就像这个设计一样

但无法辨认

1. 右上角和右下角
2. 渐变色
3. 阴影

我现在所做的是在下面的代码片段上，请检查并指导我

.container {
		width: 350px;
		border: 1px solid #CCCCCC;
	}
	.left-nav {
		list-style-type: none;
	}
	.left-nav li {
		width: 250px;
		height: 50px;
		margin: 0 0 10px;
	}
	.left-nav li a {
		background-color: #030406;
		line-height: 50px;
		color: #FFFFFF;
		text-decoration: none;
		text-align: center;
		display:  block;
		border-top-left-radius: 5px;
		border-bottom-left-radius: 5px;
		letter-spacing: 1px;
		-webkit-box-shadow: 0 7px 4px -4px #1c8eff;
  		   -moz-box-shadow: 0 7px 4px -4px #1c8eff;
  				box-shadow: 0 7px 4px -4px #1c8eff;
	}
	.left-nav li a:hover {
		background-color: #000D51;
	}

<div class="container">
		<ul class="left-nav">
			<li><a href="">Home</a></li>
			<li><a href="">About Us</a></li>
			<li><a href="">Services</a></li>
			<li><a href="">FAQs</a></li>
			<li><a href="">Contact Us</a></li>
		</ul>
	</div>

这是我的尝试，试图尽可能接近匹配。

一切都是关于内部渐变、阴影和边框的小细节。
