What is a breakpoint in responsive Web design?

Answer 1

It’s when the contents start to break and need to use media query to change the layout or design.

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

percentage is a responsive unit, the width will adjust automatically based on its parent width.

Question 3
