Footer top padding

Site URL: https://walrus-springtail-ljhd.squarespace.com/

Hi, I have tried and tried to set the padding for the site footer (v7.0) and failed.  I have managed to adjust the left and right margins but cannot seem to control the top and bottom padding.  Please can someone help?

thanks

footer#footer {

    margin-bottom: 0 !important;
}

Thanks Tuanphan.  I just got it before seeing your post using #page margin-bottom:0.  But I will keep your reply to hand in case my solution causes any other problems.
