Changing border color on a button?

I added a newsletter block to the bottom of my portfolio with a button to sign up. Is there a way to edit the border color, or remove it entirely? Here's my website for reference: https://www.jadejohnsonillo.com

button.newsletter-form-button.sqs-system-button.sqs-editable-button-layout.sqs-editable-button-style.sqs-editable-button-shape.sqs-button-element--primary {
    border-color: transparent !important;
}

 

It worked perfectly, thanks!
