Title: Remove column offset with responsive grid breaks

I was using explicit column size and an offset to create a horizontally centered box on larger screens and found that the responsive break classes don't zero out column offsets. This change fixes that.

I don't think there is any use case that you need to keep the column offset with responsive break point?
