How to change background color for middle footer on fairfield (Brine) template?

I am working on this site: https://perseverancetrailrun.squarespace.com (pwd: checkitout)

And need to get the background colour on the middle footer to be white so that I can add a bunch of logo images.

@danieljs I saw that you helped with a similar issue with regard to background colour but the CSS didn't work on this site. It may be because I don't know what the footer is called in the coding.

Thanks for your help!

@Arran That password doesn't seem to work. Try this in Design > Advanced > Custom CSS and let me know how you get on:

.Footer-middle {
background-color: white;
}

Thanks so much @danieljs . That worked except it doesn't go all the way across. It's more of a large white square. And text doesn't show up :)

@Arran Great, can see it now – delete the earlier CSS and try this instead:

#footerBlocksMiddle {
 color: black;
 background-color: white;
 margin: 0 -2%
}

Might need to play with the -2% value to get it looking right; the border is set for the whole footer so it'd take a little more work to get the middle section full-width automatically.

Thanks again @danieljs. It's getting there but still not all the way out to the edges. I am wondering if it would be better/possible to add a block ABOVE the top footer for my logos? Have you done that before?Cheers,Arran

Thanks soooo much!  I have been trying to get my footer color full width!  YAY!!
