CSS issue with div wrapping another - html

Question

I have a problem that I cannot manage to wrap my section properly.
I have a div "container" that with a php part is populated by few divs and I don't know how to properly wrap it with the border:solid of my created div.
html/php part
<div class = "listaCarrello" id ="listaCarrello "style="display: <?php echo !isset($_GET['riepilogo'])&&isset($_SESSION['username'])? "block":"none"?>">
<?php
$isEmpty = true;
foreach ($_COOKIE as $key => $val) {
$query = $connection->query("SELECT * FROM prodotto WHERE IDProdotto = $key");
if ($query != null) {
$isEmpty = false;
$row = $query->fetch_assoc();
echo "<div class = \"elemCarrello\">";
echo "<p class=\"nomeCarrello\">" . $row['nomeProdotto'] . "</p>";
echo "<div class = \"imgCarrello\">";
echo "<img src = \"img/" . $row['immagine'] . "\" alt=\"" . $row['nomeProdotto'] . "\"height=\"150px\" width=\"150px\">";
echo "</div>";
echo "<div class=\"prezzoCarrello\">";
echo "<p>Prezzo unitario " . $row['prezzo'] . "</p>";
echo "<p> Quantità: " . $val;
echo " - Prezzo totale: ";
echo "€" . $row['prezzo'] * $val . "</p>";
$totale = $totale + ($row['prezzo'] * $val);
echo "<p> Modifica la Quantità: ";
echo "<input type='number' id = 'quantita' name='quantita' value='" . $val . "'>";
echo "<button onclick='refreshCookie($key, document.getElementById(\"quantita\").value)'>AGGIORNA</button>";
echo "</div>";
echo "<button class='eliminaCarrello' onclick='eliminaCookie($key)' style='background: white'> <img src='img/elimina.png' height='50' width='50'> </button>";
echo "</div>";
}
}
?>
</div>
<?php
if (!$isEmpty) {
echo "<div class='checkOut'>";
echo "<p>Totale: €" . $totale . "</p>";
echo '<button id="2ndphase" onclick="goToAddress()">AVANTI</button>';
echo "</div>";
}
?>
css part
.listaCarrello{
border:solid;
border-color: lightgray;
border-radius: 10px;
text-align: center;
margin-top: 5px;
width: 99%;
margin-bottom: 5px;
padding-bottom: 50px;
}
.elemCarrello{
margin-top: 5px;
width: 99%;
text-align: left;
float:left;
display: block;
margin-bottom: 5px;
border: solid;
margin-left: 5px;
border-radius: 10px;
}
.nomeCarrello{
padding-left: 10px;
font-weight: bold;
}
.imgCarrello{
float: left;
padding-left: 10px;
}
.eliminaCarrello{
margin-top: -13px;
margin-bottom: 10px;
}
