I want to add an image and a button on a form post-submit

Hello!  I am trying to recreate this on a post submit form in squarespace

for this i would need to edit text size, add an image and a button

is this possible?

thanks in advance!

You can render HTML in the form post-submit, so you would need to code this with styles baked in, and you could achieve that look.

As a starting point:

<div style="text-align:center;">
  <h2 style="color:teal; font-weight:600;">Message Sent</h2>
  <img src="">
  <p>
    Thank you for your interest in us!

    A member of our team shall be in touch shortly.
  </p>
  <p style="padding:12px 20px; background-color:teal;">
    <a href="/home">Go to homepage</a>
  </p>
</div>

You'll need to adjust the styling, upload and reference the image you want, etc.
