FAQPage Schema
How do I automate UI/UX review across mobile and desktop viewports?

Automate UI/UX review by running automated visual captures across mobile to desktop viewports, which identifies responsive layout issues and generates a prioritized, actionable report. It scores issues to guide design polish and fixes.

How does axe-core accessibility testing work for web apps?

Axe-core accessibility testing works by integrating automated checks aligned with WCAG standards to identify accessibility issues in web apps. It analyzes the rendered DOM to produce structured findings for prioritized fixes.

Can I use playwright-core to capture screenshots for responsive design testing?

Yes, you can use playwright-core to capture screenshots for responsive design testing across multiple viewports. The skill uses this dependency to automate visual capture and review layouts from mobile to desktop.

What is the best way to run pre-launch UI validation and regression tracking?

The best way to run pre-launch UI validation is to execute an autonomous review that captures visuals, checks accessibility with axe-core, and tracks regressions across iterations. It produces a Lighthouse-like performance overview and prioritized action plan.

Does automated accessibility checking replace manual WCAG review?

Automated accessibility checking with axe-core does not fully replace manual WCAG review, but it identifies and prioritizes a wide range of visual and structural issues. It serves as a baseline for post-design changes review and validation.

Why does my responsive layout break across different viewports?

Responsive layouts break across viewports due to CSS or structural issues that automated visual capture can identify. Running a multi-viewport UI/UX review scores these layout issues and provides an actionable report for fixes.
