Despite trying to center-align the div using style="text-align: center;", display: block, and align="center", none of these methods seemed to work for me. Here is the code including all attempts:
<div align="center" style="text-align: center;">
<script src="https://donorbox.org/widget.js" paypalExpress="false"></script><iframe allowpaymentrequest="" frameborder="0" height="900px" name="donorbox" scrolling="no" seamless="seamless" src="https://donorbox.org/embed/ondecc?default_interval=o" style="min-width: 310px; max-height:none!important margin: 0 auto; display: block;" width="100%"></iframe>
</div>
And here is the original code:
<script src="https://donorbox.org/widget.js" paypalExpress="false"></script><iframe allowpaymentrequest="" frameborder="0" height="900px" name="donorbox" scrolling="no" seamless="seamless" src="https://donorbox.org/embed/ondecc?default_interval=o" style="min-width: 310px; max-height:none!important" width="100%"></iframe>
It's worth mentioning that I am attempting this within Bootstrap.
