`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.
