I was able to figure this out. I added the following css style to my theme.css
.wrapper {
display: grid;
grid-template-columns: 1fr 1fr;
grid-auto-rows: minmax(100px, auto);
}
This particular css style splits the available space into 2 equal columns and makes rows a minimum of 100px tall, but they can get larger if the content needs the space. Here is a good resource
Once you have this you can work with div to get them in columns and rows.
Example:
<div class="wrapper">
<div>
Content
</div>
<div>
Content
</div>
</div>
