在我的网站上，一个特定页面的徽标被向下轻推了几个像素，而在所有其他页面上却没有。所有页面的代码都是相同的（至少我认为是），所以我不确定是什么导致了问题。
这是工作与非工作的屏幕截图：
在职的：
非工作：
两者的代码如下所示，但是由于某种原因，其中一个页面无法正确呈现
<body>
<div class="wrapper"><?php include("include/header.php"); ?>
header.php：
<header id="header">
<div id="logo">
<h1 class="hidden">Welcome</h1>
</div><!-- #logo -->
<?php include("getstageinfo.php");
switch ($currentStage)
{
case "0":
$home ="period0.php";
break;
case "1":
$home ="period1.php" ;
break;
case "2":
$home ="period2.php" ;
break;
case "3":
$home = "period3.php";
break;
}
?>
<nav id="nav">
<h1 class="hidden">Main Navigation</h1>
<a class="nav-item current" href="<?php echo $home ?>">HOME</a>
<a class="nav-item" href="news.php">NEWS</a>
<a class="nav-item" href="accounts.php">ACCOUNTS</a>
<a class="nav-item" href="logout.php">LOG OUT</a>
<div id="nav_edge"> </div><!-- #nav_edge -->
</nav><!-- #nav -->
</header><!-- #header -->
