Hello Sanjip,
Thanks for the very fast reply and solution you came up with.
Unfortunately the CSS code you posted did not make disappear the background color. I tried it several times to paste it before i klicked ‘save changes’ in the Custom CSS section, and I even tried to change the CSS code slightly, but nothing happened.
But your code helped me to make disappear the background via another way. I switched to the “edit” button in Appearance to make changes in the style.css file. Searched for this “service-item” text in the style.css and there I put “none” instead of the color-code. Apparently this made disappear the background anyway. So it’s fixed now.
Thanks for guiding me in finding the solution for this issue.
