Add Margin and Padding utility helper scss class's using for loop

By using for loop on scss we can generate the class for margin and padding for top , bottom, left and right

.mt-5 {margin-top: 5px;}.mx-5 {margin: 0 5px;}.......pb-30{padding-bottom:30;}.py-30 {padding:  30px 0;}

Hope this util class generation will help to implement spacing in scss.
