Title: Variable grid column and gutter width in responsive design mode

Instead of hardcoding the values of the grid column and gutter width I took the ratios of the default values and the existing ones and multiplied it by the corresponding variables. Without customization the results should be the same. Let me know if there's a better way. Thanks.
