Footer background colour and footer menu

Hello, how can I change the background colour of my footer to white? i have already tried adding this to Additional CSS and it hasn’t worked
.site-footer {
background: #000000;

Also my footer menu is not in one line, how can i make it so it lines up?

Thanks, Shianne

Hello there,

I hope you are doing well today.

Could you please provide a link to your website so that I can inspect it?

You can use the following CSS code to change the footer color by going to Appearance > Customize > Additional CSS and pasting it there.

/*Footer color*/
#colophon {
    background-color: red;

Best Regards,
