how to give table (cart page) round corners

Hey community,

I am currently working on a woocommerce page and I can't seem to give my table (cart page) real rounded corners. This is my CSS:

.shop_table.shop_table_responsive.cart.woocommerce-cart-form__contents {
border: 1px solid #18615B;
border-radius: 10px;
}

The picture shows the result. Any hints how to get this done?

Using the visual builder does create a better result.

 

Here's the URL: https://www.wearex.net/login/

Since the shop is still in production and only available for registered users, you will need this login data:

US: testuser
PW: Fg6%L&J8^Cvlxxpsaspu!vj!

Add any item to the cart and you will see the table underneath "cart".

Thanks!
