When customizing the footer on a Hub site, can you change the background color? I have very limited .css knowledge and I was given the .css file for our website to use. This .css file worked in customizing the header, but it does not seem to work well in the footer customization. In particular, I'd like to have a background color for the footer, I see where it states the color in the .css file, but it doesn't work.
Here is the part of the .css file that seems to be stating what the background color should be:
padding: 1em 3%;
margin: 0 auto;
