Quick answer
A responsive website mockup should use an authentic capture for each breakpoint. Place those captures in matching devices, make one viewport the lead, and animate the scene to show how the design adapts rather than repeating one desktop image at different sizes.
When this workflow is useful
This presentation works for agency case studies, portfolio projects, responsive redesign launches, stakeholder reviews, design-system documentation, and SaaS products with mobile and desktop experiences.

Step-by-step workflow
- Capture representative breakpoints. Prepare phone, tablet, and desktop screenshots or recordings from the real responsive layout.
- Choose the lead breakpoint. Decide which experience best communicates the result and give it the strongest scale or camera position.
- Assign media by device. Use separate media for every screen and check that navigation, typography, and crop reflect the intended breakpoint.
- Coordinate the reveal. Introduce the group, then use individual timing or a camera move to give each breakpoint a readable moment.
- Export for the case study. Create a wide hero version, a closer detail clip, and a still frame so the project can work across portfolio sections.
Decisions that improve the result
Same page versus workflow
You can show one page adapting across sizes or different steps across devices. State the purpose clearly so viewers do not misread the composition.
Browser chrome
Use it when URL or website context matters; remove it when the design needs maximum screen area.
Device count
Three meaningful breakpoints are often enough. More devices can reduce the size of every screen without adding insight.
Production checklist
- Real breakpoint captures
- One lead viewport
- Correct media per device
- Navigation state consistent
- Readable reveal
- Hero and detail exports
Frequently asked questions
Can each device show a different breakpoint?
Yes. Pro lets each device use its own screenshot or recording.
Should I include a tablet?
Include it when tablet behavior is designed and relevant. Do not add a tablet only to make the composition feel fuller.
Is this a responsive testing tool?
No. Use browser testing for validation; use the mockup video to communicate the finished responsive experience.
