FOOTER HAS DOUBLE SPACING

Site URL: https://www.arcagalerie.com/

Hello! My footer is defaulting to double spacing, and I'd like for it to be single spacing. Any ideas on how to change this?

Also, how do you remove the underline for hyperlinks?

Thanks!

@GGNY You can add this code under Website > Pages > Website Tools > Custom CSS

#footer-sections {
    h1, h2, h3, h4, p {
        margin: 1em 0;
    }
    a {
        text-decoration: none;
    }
}

thank you!!
