[Wordpress] Trying to delete border nowhere to find in the CSS

[Bobbutterfly 0]

Hello guys!

I have an issue on my website. As you can see on the inclosed picture, I have white borders on my footer. But they appear only on phone screens and I can't see where they are located in the CSS...

Any idea please?

Thank you in advance!
