Newsletter Block Spacing

Site URL: https://magnolia-hawk-8wyh.squarespace.com/

I have a newsletter block in my footer. The spacing between the header and the sign up is too large because I don't have a description. Is there a way to make the description space not visible or reduce the spacing?

footer.sections .newsletter-form-header-description {
    display: none;
}

Also, I see this page, on tablet, left padding > right. Do you want to center them?

@tuanphan. Thanks for pointing that out! I definitely want them centered. What is the code for that?

Try adding to Home > Design > Custom CSS

@media screen and (max-width:991px) and (min-width:768px) {
.flip-card {
    width: auto;
}
}
