當網站采用桌面和平板電腦解析度時，文本輸入對齊良好，但是當我為移動設備調整其大小時，我得到了這個輸出。
<form name="orderForm" method="post" action="updateList.php">
<div class="card h-100">
<div class="card-body p-4">

<input type="hidden" name="stockID" value="<?php echo $row['stockID'] ?>">
<span class="card"><img class="img-fluid card-img-top" src="<?php echo $row['image'] ?>" alt="No image yet"></span>
