BACKGROUND ELEMENT JUXTAPOSES WITH SOCIAL MEDIA BUTTONS VIEW ON MOBILE VIEW

Background V-shaped element juxtaposes with Social media buttons (Ultimate Social Media Icons PLUS plugin free version) set at the bottom of the content view on mobile view only. More specifically the white area of the content cuts through the logo as if as the white part is on top of the logo. This happens with the bottom V-shaped white element (<path d=”M 0,150 0,0 1925,0″></path>). How can I have the buttons showing on top of the white V-shaped content? Maybe by controlling the z-axes somehow?

I use a child theme.

Any help?
