<div class="cognito"> <script src="https://services.cognitoforms.com/s/kqtsv-uype2bbu47xu3lpw">    </script> <script>cognito.load("forms", { id: "1" });</script></span> </div> 

you can add below script before end of span tag.

<script type="text/javascript">     window.onload = function() {         document.queryselector(".cognito .c-action").style="text-align: center;float:none;";     };     </script>
