To audit your UI for accessibility and mobile responsiveness, evaluate semantic HTML structure, keyboard navigation, screen reader support, and responsive scaling from small screens to large displays. This identifies barriers ensuring interfaces are usable across devices.

The best way to implement responsive typography is using the CSS clamp() function. This function allows you to set minimum, preferred, and maximum font sizes, ensuring text scales fluidly across mobile and large displays without breaking layout consistency.

Mobile-first design improves Core Web Vitals by prioritizing critical rendering paths and performance-focused CSS for small screens. This reduces initial load times and layout shifts, ensuring fast, user-first interfaces across all viewport sizes.

Yes, you can build design-system-consistent components without external dependencies. The Skill provides patterns for semantic HTML and CSS authoring to maintain visual cohesion, ensuring components remain cohesive without requiring third-party UI libraries.

Semantic HTML is needed for dark mode support because it provides the structural foundation for accessible theming. Proper semantic elements ensure screen readers correctly interpret content context when visual cues change in dark mode.

You should not use clamp() for responsive typography when targeting legacy browsers lacking CSS math function support, or when strict pixel-perfect design requirements demand fixed sizing over fluid scaling. Otherwise, it is safe for modern web apps.
