How to make Rich Text Form Field - Responsive

I am struggling to get a rich text field on a form to be responsive I have tried a couple of things in the CSS but nothing seems to work.  Any suggestions.

Right now I am trying to put it in a table so disregard that in the HTML Code for the field:

<div>
<table width="402" height="47">
<tbody>
<tr>
<td style="text-align: center;"><span>By clicking the “Submit” button, you agree to receive communications from KVH, its family of companies, and business partners regarding KVH products and services via email.

</tr>
</tbody>
</table>
</div>
