How to fix footer image resizing for mobile view using CSS?

[Cangelos772]

So I added a background Image in my footer but when it goes to mobile sizing, it looks completely different. How do I css code it to look the same. I've tried responsive, position relative, etc, I believe in the theme its set as a flex container. Unsure what to try. Images of code as well as whats going on as reference. Im more worried about the background image responding that way than I am the text blocks acting that way. BUT i would eventually like to clean that whole section up. ALSO, I have setup lazysizes on the homepage EXCLUDING this image, how would I add that in to this image?

yes please try this code

#footer .f_mid {
background-repeat: no-repeat;
    background-size: cover;
}

@KetanKumar so, that DID work, but how the footer expands vertically, it leaves this huge whitespace after the image. Do you know if i can set it so when the site is set in moble it changes the background to a simple grey to compensate for this?

@KetanKumar I took it off as a lot of our users on the site are mobile. Is there a way to state that once browser size reaches a certain point, that image is subbed out or overlayed with just a grey color?
