Reproduce the footer layout at viewports below 997px using issue #618 and compare it with the layout above that breakpoint. Locate the footer's responsive styling, identify the excessive right padding in the vertically stacked Docs, Community, and Projects sections, and verify that the spacing is corrected without changing the layout above 997px.
