How can I change the styling of my submit button?

I used a template to create my JotForm, and now I can't seem to change the button from a circular design to a classic rectangular button. How can I change it so it looks like this:

We cannot directly change the style of the theme styled button. As a workaround you can add the next CSS to override the styles:

.form-all .form-submit-button {
transform: none !important;
background: none !important;
color: #af2626 !important;
font-size: 16px !important;
border-radius: 3px !important;
border: 3px solid #af2626 !important;
width: 150px !important;
height: 50px !important;
}
.form-buttons-wrapper:before {
width: 0 !important;
}
.form-buttons-wrapper:after {
width: 0 !important;
}

This should change the style on the live form.

Thank you.
