我有这个代码，但我如何将图片放在中心，如何更改字体大小以及如何将其放在中心。我知道如果HTML标记不在PHP标记内，但在这段代码中，HTML标记在PHP内，如何使用CSS。
<html>
<head>
<title> page 1</title>
<body>
<?php
session_start();
$get_id= $_GET['id'];
$get_pass = $_GET['pass'];
$name = "";
$_SESSION['user_id']=$get_id;
$_SESSION['user_pass']=$get_pass;
$con = mysqli_connect('localhost', 'root', '');
if(!$con)
{
die("not ok");
}
mysqli_select_db($con,"uoh");
$q = " SELECT * FROM student WHERE id = " . $get_id ." and password = " . $get_pass;
$result = mysqli_query($con , $q ) ;
if($row = mysqli_fetch_array($result))
{
if ($row["major"]=="computer engineerig")
{
echo "welcome ". $row["name"];
echo " and your id is ".$row["id"];
echo " and your major ".$row["major"];
echo "<br />";
echo '<a href="tran.php?page=A"><img src="tran.png"/></a>';
echo '<a href="course_list.php?page=A"><img src="courselist.png"/></a>';
echo '<a href="comp.php?page=A"><img src="comp.png"/></a>';
}
elseif ($row["major"]=="software engineerig")
{
echo "welcome ". $row["name"];
echo " and your id is ".$row["id"];
echo " and your major ".$row["major"];
echo '<p>academic transcript <a href="tran.php?page=B">here</a></p>';
echo '<p>courses list<a href="course_list.php?page=B">here</a></p>';
echo '<p>student compliance <a href="comp.php?page=B">here</a></p>';
}
else
echo "your ID not found";
}
?>
</body>
</html>
有几种方法可以做到这一点。为了简单起见，您可以使用<style>标记。
对齐图像：
echo '<p style="text-align:center"><a href="tran.php?page=A"><img src="tran.png"/></a></p>';
缩小字体大小并居中对齐文本：
echo '<p style="font-size:10px;text-align:center">academic transcript <a href="tran.php?page=B">here</a></p>';
