Footer customisation in the Evolve theme.

Hi,

I’ve just started building the website for a project.

I’d like to add a logo to the footer of my webpage (https://aarc-project.eu/).

I tried to customise the CSS but it didn’t really work. I only managed to get a link to a word, but no image.

Does anybody know how to change the colour background of the footer only?

Any help would be greatly appreciated!
