Order_summary_challenge - Frontend-Mentor

Hello everyone, it has been a few days since I posted it here. I have tried increasing the width, height and the size of the rem unit, but I cannot match my solution to the screenshot above.

Can you please tell me if there is any problem in my code which is causing the above mentioned issue? and one more question, do we need to make our solution match the scale of the screenshot?

DR: (I do not have the design files for these challenges, as I am not a pro member).
