Examples for page layouts with different column widths, full width, 3/4 and 2/3. Mixing all variations in one page is actually not recommended, though.
Design-wise this is more of a desktop thing, on mobile devices most of the columns will be full width. All columns here are .card to be visible, which wouldn‘t leave much room for text in 1/6 and smaller.
