Embedded Spreadshirt not going full width

Howdy Yall,
I have been trying to get my spreadshirt shop to go full width the below HTML and JS provided via spreadshirt.com. No matter what I do I can’t seem to eliminate the padding on either side of the embedded store. See screenshot HERE. On the spreadshirt side, everything is set to full width, however when I inspect I see some padding that I can’t see to get rid of.

Live link to the page is HERE.

<div id="myShop">
    <a href="https://shirts-life.myspreadshop.com">shirts-life</a>
</div>
<script>
    var spread_shop_config = {
        shopName: 'shirts-life',
        locale: 'us_US',
        prefix: 'https://shirts-life.myspreadshop.com',
        baseId: 'myShop'
    };
</script>
<script type="text/javascript"
