Challenge 1: Resizing a Frame Isn't Like Resizing an Artboard — Solution Walkthrough

The answer:

Per this chapter's own material, a Vector Graphics artboard simply
marks a fixed area with no built-in resizing logic for its own
contents — resizing the artboard itself doesn't move or reshape
whatever's inside it. A Figma Frame is genuinely different: it can
define constraints controlling how its own children behave when the
Frame is resized — staying pinned to an edge, scaling proportionally,
or stretching to fill available space.

Why the designer's expectation doesn't carry over:

The designer is applying Vector Graphics' own artboard behavior (a
purely passive boundary) to a Frame, which is actually a responsive
container as well as a boundary. Resizing a Frame can genuinely
reposition, resize, or reflow its own child elements, depending on
whatever constraints have been set on them — behavior an artboard
simply has no equivalent for.

Why this matters for actual UI work:

This dual-purpose behavior is exactly why Frames exist — designing a
screen that needs to adapt across different device sizes requires
exactly this kind of responsive container, which a plain artboard was
never built to provide.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that a Frame's own constraint-driven resizing
behavior is correctly distinguished from an artboard's purely passive,
boundary-only behavior.
