i am making a hotel booking page. this is the overview where customers can see al rooms, and check some info before getting sent to a details page of a certain room. where they can make a reservation. the problem is. some room descriptions are bigger than others. But i want every room div to have a static size. as you can see in the screenshot i got that figured out but there is this white gap at the bottom of each div. How can i make it so the white gap is inbetween the room description and the other details in the table instead of at the bottom?
Code:
<?php
    include_once "db.php";
    include "preset.php";
    $db = new Database();
    $room = $db->select("SELECT * FROM room");
?>
<body>
    <div class="container">
        <div class="room_container">
            <?php foreach ($room as $rows){ ?>
                <div class="col-4">
                    <div class="top">
                        <h3><?php echo $rows["roomName"]; ?></h3>
                        <p><?php echo $rows["roomDescription"]; ?></p>
                    </div>
                    <table class="table table-striped">
                        <tbody><tr>
                            <td>Soort Kamer:</td>
                            <td><?php echo $rows["typeOfRoom"] ?></td>
                        </tr>
                        <tr>

                        </tr>
                        <tr>
