Thanks for your reply. The code has changed the background colour as requested black as shown in your code which I have changed to #f7f7f7 which is working correctly.
Is it possible to make the inner row to white the row id on wordpress is 1574504180660 I have modified the css which doesn’t have the required effect. Ideally it would be a css to have the row colour white with a radius of 15px but the white back is more imporant than the radius.
