Adelle Theme Footer Help

Hi,

I am trying to customize my footer on The Adelle theme. I am unsure why I can’t edit it using the Google develop tools, my footer tab disappeared. I just want the foot to be a rectangle (no cutouts) and for it to be all one color. Thank you in advance for you help.

P.S.
these are the codes in my CSS editor
.footer-copy {
background: #ff957d;
}

.footer-copy {
color: #fff;
}
.footer-copy a {
color: #fff;
}

p.footer-copy:before, p.footer-copy:after {
border: #ff957d;
}
