Responsive Validation

Systematic validation across a device viewport matrix. Goes beyond basic screenshot comparison — validates layout behavior, touch targets, content parity, overflow, and responsive-specific interactions at every breakpoint.

When to Use

• After implementing responsive layouts
• Before mobile launch or responsive redesign
• When users report layout issues on specific devices
• During cross-device QA for web applications
• After CSS grid/flexbox refactoring
