modern-reset

The definitive zero-specificity CSS reset and normalization layer for the 2026 modern web.

modern-reset is a high-performance, accessibility-first foundation designed to eliminate cross-browser inconsistencies while maintaining a specificity of 0. It bridges the gap between traditional normalize.css and the advanced requirements of modern layouts like React, Next.js, and fluid-first responsive design.

🚀 Why modern-reset?

In 2026, old-school resets are no longer enough. modern-reset solves the "Hidden Layout Shift" and "Specificity War" problems.

| Feature | modern-reset | Traditional Resets | | :--- | :--- | :--- | | Specificity | 0 (Zero) — uses :where() everywhere. | High — you have to fight to override. | | Layout Safety | scrollbar-gutter: stable & overflow-x: clip. | Content jumps when scrollbars appear. | | Resilient Media | display: block & max-inline-size: 100%. | Images cause layout shifts and overflow. | | Micro-Typo | text-underline-offset & text-decoration-skip-ink. | "Messy" underlines that cross through letters. | | Frameworks | isolation: isolate on roots (#root, #__next). | Z-index bugs and stacking context leaks. | | Modern UX | field-sizing: content & interpolate-size. | Requires JS for auto-expanding textareas. | | Typography | text-wrap: balance/pretty & ex scaling. | "Widows" in headers and broken font rhythm. | | Logical Style | max-inline-size & min-block-size (dvh). | Hardcoded px/vh values that break on mobile. | | Scroll Sync | scrollbar-gutter: stable & scroll-behavior. | Layout "jitter" when scrollbars appear/disappear. |

🛠 Features in Depth

🧩 Zero Specificity Theory

Every rule in modern-reset is wrapped in :where(). This ensures that any selector you write in your own CSS—even a simple p or h1—will instantly override the reset. No more !important hacks.

🛡 Defensive Layout Patterns

• Scrollbar Stability: Prevents layout "jitters" by reserving space for the scrollbar.
• Horizontal Safety: overflow-x: clip prevents unwanted horizontal scrolling while remaining compatible with position: sticky.
• Isolation Layers: Automatically applies isolation: isolate to #root and #__next to prevent stacking context bugs in frameworks.

♿ Accessibility (A11y) & Performance

• Reduced Motion: Respects system preferences for animations.
• Improved Focus: Accessible :focus-visible styles for keyboard navigation.
• Touch Optimization: Eliminates tap-delays on touch devices without disabling zoom.
