我是php和bootstrap的新手,我正在尝试创建门户网站管理员。我已经使用引导程序示例创建了我的第一页,但是我不知道为页面创建“开始”点不会被导航栏覆盖,而且我也无法更改“欢迎”文字的颜色如果我使用文字class="text-white"
。
我的代码:
<?php
session_start();
include_once("security.php");
include_once("connectionDB.php");
?>
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<link rel="icon" href="img/favicon.ico" type="image/x-icon">
<title>Menu</title>
<!-- Bootstrap core CSS -->
<link href="css/bootstrap.min.css" rel="stylesheet">
<!-- Custom styles for this template -->
<link href="css/signin.css" rel="stylesheet">
</head>
<body>
<?php
$SQLQuery = "SELECT id,filename,starttime,endtime,fromnumber,tonumber FROM gravacao ORDER BY starttime DESC";
$QueryResult = mysqli_query($conn, $SQLQuery);
?>
<nav class="navbar navbar-expand-md navbar-dark bg-primary fixed-top">
<a class="navbar-brand" href="#">Home</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarsExampleDefault">
<ul class="navbar-nav mr-auto">
<li class="nav-item dropdown">
<a class="nav-link text-white" href="#" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Configuration</a>
<div class="dropdown-menu" aria-labelledby="dropdown01">
<a class="dropdown-item" href="#">Users</a>
<a class="dropdown-item" href="#">List</a>
</div>
</li>
<li class="nav-item dropdown">
<a class="nav-link text-white" href="#" id="dropdown01" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Reports</a>
<div class="dropdown-menu" aria-labelledby="dropdown01">
<a class="dropdown-item" href="list.php">List</a>
</div>
</li>
</ul
<a class="text-white">Welcome <?php echo $_SESSION['Name']; ?></a> 
<form class="form-inline my-2 my-lg-0" action="sair.php">
<button class="btn btn-outline-light my-2 my-sm-0" type="submit">Logout</button>
</form>
</div>
</nav>

<tbody>
<?php
while($rows = mysqli_fetch_array($QueryResult))
{
echo "<tr>";
echo "<td>".date("d-m-Y H:i:s",strtotime($rows['starttime']))."</td>";
echo "<td>".date("d-m-Y H:i:s",strtotime($rows['endtime']))."</td>";
echo "</tr>";
}
?>
</tbody>
</table>
</main><!-- /.container -->
<!-- Bootstrap core JavaScript
================================================== -->
<!-- Placed at the end of the document so the pages load faster -->
<script src="js/jquery-3.3.1.slim.min.js"></script>
<script>window.jQuery || document.write('<script src="../../assets/js/vendor/jquery-slim.min.js"><\/script>')</script>
<script src="js/popper.min.js"></script>
<script src="js/bootstrap.min.js"></script>
</body>
</html>
我该如何解决?非常感谢你!
