this is how short code looks like
[stripe name="My Store" description="My Product" amount="1999" billing="true" shipping="true"]
you can use a div tag:
<div id="button>"[stripe name="My Store" description="My Product" amount="1999" billing="true" shipping="true"]</div>
<style>
#button {
text-align: center;
margin: auto;
}
</style>
