I have a table and whenever there are too many rows it goes off the bottom of the page and exceeds its containers height.

<body>
<div class="myContainer">
<table class="scrolldown">
<!-- Table head content -->
<thead class="test1">
<tr>
<th>Heading 1</th>
<th>Heading 2</th>
</tr>
</thead>
<!-- Table body content -->
<tbody class="test2">
<tr>
<td>Content</td>
<td>Content</td>
</tr>...
</tbody>
</table>
</div>
<body>
CSS
.myContainer {
outline-style: solid;
outline-color: #c7d2fe;
height: 100px
}
tbody td,
thead th {
width: 200px;
border-right: 2px solid black;
}
td {
text-align: center;
}
How can I make it so that the table becomes scrollable once it would extend past its containers height?
