Question

我想我有一些错误，我的眼睛无法找到问题。所以我要求你帮助我找到我的问题 - 强调不要出现在悬停中。

Answer 1

你必须添加文字装饰：下划线; 悬停物品

Answer 2

我不太清楚为什么你使用新的<div>元素作为下划线，但要明白这一点：

无法在当前的HTML结构中选择悬停的div。

为什么不在悬停时向初始text-decoration: underline添加简单的<li>？然后，您可以简单地解决<a>标记，我在此更新了您的代码：

body, div, span, ul, li {
	margin:0;
	padding:0;
	font-family:"Agency FB";
}

li, a {
	list-style-type:none;
	text-decoration:none;
	color:white;
	font-size:14px;
}

li {
	display:inline-block;
	margin:28.5px 5px 5px 35px;
}

li a:hover {
	border-bottom:3px solid #FFB700;
}

.page, .header {
	padding:0;
}

.page {
	border:1px solid black;
	height:1200px;
	min-width:1265px;
	width:100%;
}

.header-bg {
	height:655px;
	border:1px solid black;
	background:url("http://pokkers.lv/photo-bg.jpg");
	background-size:cover;
}

nav {
	display:block;
	width:100%;
	height:75px;
	background-color:rgba(0,0,0,0.2);
}

.main-nav {
	width:380px;
	height:75px;
}

.left-nav{
	margin-left:200px;
	position:absolute;
	top:0;
}

.right-nav {
	margin-right:200px;
	float:right;
}

.side-div {
	border:1px solid white;
}

<body>
	<div class = "col-md-12 page">
		<header class = "col-md-12 header">
			<div class = "header-bg">
				<nav>
					<div class = "left-nav main-nav">
						<ul>
							<li id = "news"><a href = "#">NEWS</a></li>
							<li id = "forums"><a href = "#">FORUMS</a></li>
							<li id = "blogs"><a href = "#">BLOGS</a></li>
							<li id = "statistics"><a href = "#">STATISTICS</a></li>
						</ul>
					</div>
					<div class = "right-nav main-nav">
						<ul>
							<li><a href = "#">SERVERS</a></li>
							<li><a href = "#">BANLIST</a></li>
							<li><a href = "#">MARKET</a></li>
							<li><a href = "#">CONTACTS</a></li>
						</ul>
					</div>
				</nav>
			</div>
		</header>
	</div>
</body>

Answer 3

以下是一个如何使用以下内容完成此操作的示例：在伪元素之后，因为您拥有的当前HTML结构将不允许您将鼠标悬停在链接上，并显示一个div（或任何其他元素）是<a>

的孩子

CSS：

  .main-nav a {
    position: relative;
    text-decoration: none
  }

  .main-nav a:after {
    content: '';
    display: none;
    height: 2px;
    background: #f00;
    width: 100%;
    bottom: 0px;
    left: 0px;
    position: absolute;
  }

  .main-nav a:hover:after,
  .main-nav a:focus:after {
    display: block;
  }

演示HTML

<ul class="main-nav">
  <li>
    <a href="#!">
      Link
    </a>
  </li>
</ul>

CSS悬停不起作用（需要显示下划线）
