Button not centre on mobile version

Site URL: https://www.bijouxcreative.com/branding

I have a button on an image overlap which is aligning left on the mobile version of the page (screenshot attached).

Please could somebody help me centre it?

Thanks so much!

Add to Page Settings > Advanced > Header

<style>
  @media screen and (max-width:767px) {
  .image-card.sqs-dynamic-text-container {
    width: 100% !important;
    margin: 0 auto !important;
}
  }
</style>
