Modify style of 'Pay with Card' Stripe button : <p>Is it possible to modify style of "Pay with Card" Stripe button? I've tried modifying by,</p>

<ul>
<li>adding a new class defined in external style sheet</li>
<li>modifying its own class of <code>stripe-button</code> in external style sheet</li>
<li>and editing it inline with <code>style=""</code></li>
</ul>

<p>But I cannot get the button to change its style.</p>

<p>It looks like it might be possible with the <code>custom integration</code> instead of the <code>simple integration</code> (source: <a href="https://stripe.com/docs/checkout#integration-simple" rel="noreferrer">https://stripe.com/docs/checkout#integration-simple</a>), but I was hoping there was something simpler.</p>

<p><strong>Button with default style:</strong></p>

<p>Does anyone have experience with this?</p>

<p>(I'm integrating into Ruby on Rails if that makes any difference.)</p>
