Responsive Four Card Feature Section using grid and grid areas

Hi guys, I hope you are doing fine and I am glad to be here for another challenge. The thing I struggle with the most is my screen's dimensions: I work with an 1366 x 768 screen and it's making it hard for me to judge the dimensions based on the (1440 px ) design for the margins and heights. Can you please rate my code and if you have any suggestion concerning my problem i'll be very grateful. Thank you so much for your time and Happy Coding :D
