Skill Content

scaffold-html-css {Frontend} (v1.0)

"Ship pixels that perform, accessible by default."

Purpose

Production HTML5/CSS3/JS project scaffold. Semantic structure, responsive grid, design tokens, Hostinger-ready deployment. [EXPLICIT] When to use: Frontend development within the Firebase/Google/Hostinger stack.

Core Principles

Law of Semantics: HTML first, CSS second, JS third. Semantic markup is non-negotiable. [EXPLICIT]
Law of Performance: Lighthouse > 90. Lazy load images. Code-split routes. Critical CSS inline. [EXPLICIT]
Law of Accessibility: WCAG 2.1 AA minimum. Keyboard navigable. Screen reader tested. ARIA where needed. [EXPLICIT]

Core Process

Phase 1: Structure

Define page/component structure with semantic HTML5. [EXPLICIT]
Apply design tokens from .agent/.shared/design-tokens.md. [EXPLICIT]
Configure responsive breakpoints (mobile-first). [EXPLICIT]

Phase 2: Build

Implement with framework (React/Angular) or vanilla HTML/CSS/JS. [EXPLICIT]
Integrate Firebase services (Auth, Firestore listeners, Storage). [EXPLICIT]
Add loading/error states for async operations. [EXPLICIT]

Phase 3: Validate

Run Lighthouse audit (> 90 on all categories). [EXPLICIT]
Run accessibility audit (axe-core). [EXPLICIT]
Test on mobile, tablet, desktop breakpoints. [EXPLICIT]

3. Inputs / Outputs

Input	Type	Required	Description

Validation Gate

5. Self-Correction Triggers

[!WARNING] IF using div soup without semantic elements THEN refactor to semantic HTML5. IF Lighthouse < 90 THEN optimize before shipping.
