Workflow
1. Navigate to the Page
Use browser_navigate to open the target URL (usually http://localhost:3000 or whatever the dev server is running on).
2. Test Each Viewport
For each viewport size:
- Resize the viewport using
browser_navigatewith viewport parameters, or usebrowser_snapshotto inspect the layout - Take a screenshot with
browser_take_screenshot - Check
browser_snapshotfor the aria tree — look for:
- Content overflowing or hidden behind other elements
- Navigation that should collapse into a hamburger menu
- Text that's too small to read
- Buttons/links too close together (touch target issues)
- Horizontal scrollbars that shouldn't exist
3. Check for Common Breakage
- Overflow: Elements wider than the viewport causing horizontal scroll
- Collapsed layout: Flex/grid items that should stack on mobile but don't
- Hidden content: Elements that disappear at certain sizes without a menu toggle
- Font scaling: Text that's readable on desktop but tiny on mobile
- Fixed positioning: Modals, toasts, or sticky headers that break on small screens
- Images: Oversized images that don't scale down
4. Report
Responsive Test Results:
375px (mobile): PASS — layout stacks correctly
428px (mobile): PASS
768px (tablet): WARN — nav items overlap, need hamburger menu
1280px (desktop): PASS
1536px (ultrawide): WARN — content not centered, stretched too wideFix any issues found, then re-test the affected viewports.
