Device Mockup

This lesson is part of Web Developer Tools · All levels

Summary

The device mockup places the design into the frame of a device such as a phone, tablet, or laptop to see how it looks. This tool helps to present and roughly check responsive design. The mockup is not a replacement for testing on real devices because it does not mimic all browser and device behavior. Take a look at the width of the viewport and the image scale to keep the proportions correct.

Key points

The mockup is a visualization, not a full emulation.
Common breakpoints include mobile phones, tablets, and desktops
Use the width of the viewport, not just the frame size
Test interaction on DevTools and real devices
Use high-resolution images for your presentation
