Effective HTML

Prototypes

Use interactive HTML prototypes to try product flows, behavior, and states.

A prototype lets you try part of an app before building or changing the real product. An agent can make a self-contained HTML prototype with realistic content and enough behavior to show how the flow works.

Live behavioral evidence

Exercise the states that could reverse the decision.

Path
Resolve one blocker and prepare a release.
States
Blocked, pending, failure, recovery, and ready are operable.
Boundary
The prototype demonstrates behavior without claiming a backend.

What a prototype can show

  • a multi-step flow;
  • loading, empty, error, and success states;
  • validation and feedback;
  • keyboard and mobile behavior;
  • transitions between views or modes.

It does not need to be the whole product

A useful prototype can cover one important path and the states around it. It does not need a backend, every screen, or every edge case. It should be clear which parts work and which parts are only visual.
