How does this skill improve SEO?

Search engines prioritize accessible sites; by fixing contrast and visibility errors, you improve your site's quality signals and overall Lighthouse performance score.

Can this skill fix gradient text issues?

Yes, it provides CSS fallback patterns to ensure text remains accessible to screen readers and contrast checkers while maintaining design aesthetics for modern browsers.

What does the '!' in Lighthouse mean?

It indicates that the audit failed to run completely, often due to complex CSS like filters or unusual color spaces that prevent the contrast engine from calculating scores.

Why are OKLCH colors an issue for SEO?

While modern, some accessibility tools struggle to parse them, leading to failed contrast audits which negatively impact your Lighthouse score and SEO ranking.
