Hi Caroline,
Thanks for following-up! Taking a look at your site the issue is not calendar related at all, but I’ll help out anyway this time.
Just add this lines to your theme stylesheet (located at wp-content/themes/your_theme/style.css) or use Simple Custom CSS to add it via the site backend. Here’s the code:
.cart_totals input[type=submit] {
padding: 9px 10px 9px 19px !important;
width: 90px !important;
}
.cart_totals .continue-shop {
display: none;
}
Please note that we do not support styling/theme issues, but hopefully this snippet should get things right.
Best,
Nico
