Background color for text box in element

tried copy and paste previous div elements to create same features…but, background color for question7 is not showing up, and text box is not centered

Question 7 is not showing because, another layer is on top of it. If you remove all the other layers you will see it.
Although you did use the justify-content: center; to try and center it which ussualy does work if no other elements are blocking it howver, you have several of them

Not exactly sure what you mean. What “layers” need to be removed? And what “elements” are blocking me from centering the input operation?
