Can I embed html code in my site via the "code" widget in upfront?

I want to add this code to my site

<link target='_blank' href='https://fdhq-assets.s3.amazonaws.com/widget/class_schedule/widget.css' rel='stylesheet'>
<span>
<script defer='defer' src='https://fdhq-assets.s3.amazonaws.com/widget/class_schedule/app.min.js'></script>
</span>
<div class='fd-schedule' data-fd-domain='praxisbjj' data-fd-timezone='America/Los_Angeles' data-ng-cloak='' data-service-id='17640' data-ui-view='' ng-controller='ContextController'></div>

Can I do that via the code widget on upfront?

Thank you!
Larry
