Question 2

What is the advantage of using a percentage (e.g. 50%) width instead of a fixed (e.g. px) width for a “column” class in a responsive layout?

Answer 2

it allows the page to work better on multiple screen sizes

Question 3

If you introduce CSS rules for a smaller min-width after the styles for a larger min-width in your style sheet, the CSS rules for the smaller min-width will “win”. Why is that?

css rules are apply in source order of writing so the smaller rule still fits on the bigger screen
