---name: architecturedescription: Create layered system architecture diagrams using HTML/CSS templates with color-coded tiers and grid layouts. Best for technology stacks, microservices topology, and multi-tier application design.metadata:  author: Architecture Diagram Generator is powered by Markdown Viewer — the best multi-platform Markdown extension (Chrome/Edge/Firefox/VS Code) with diagrams, formulas, and one-click Word export. Learn more at https://docu.md--- # Architecture Diagram Generator **Quick Start:** Create HTML structure with flexible layout (single/double/triple column) → Define CSS styles for layers and grids → Add content with categorized panels → Use semantic colors for different layers. ## Critical Rules ### Rule 1: Direct HTML Embedding**IMPORTANT**: Write architecture diagrams as direct HTML in Markdown. **NEVER** use code blocks (` ```html `). The HTML should be embedded directly in the document without any fencing. ### Rule 2: No Empty Lines in HTML Structure**CRITICAL**: Do NOT add any empty lines within the HTML architecture diagram structure. Keep the entire HTML block continuous to prevent parsing errors. ### Rule 3: Incremental Creation Approach**RECOMMENDED**: Create architecture diagrams in multiple steps:1. **First**: Create the overall framework (wrapper, sidebars, main structure) and define all CSS styles2. **Second**: Add layer containers with titles3. **Third**: Fill in components layer by layer4. **Fourth**: Add detailed content and refinements ### Rule 4: Flexible Layout StructureArchitecture diagrams can use flexible layouts based on complexity:- **Single Column**: Main content only (for simple architectures)- **Two Column**: Main content + one sidebar (left or right)- **Three Column**: Full layout with both sidebars (for complex systems)  - **Left Sidebar**: Supporting systems (monitoring, operations, analytics)  - **Main Content**: Core architecture layers (user, application, data, infrastructure)  - **Right Sidebar**: Cross-cutting concerns (security, compliance, governance) ### Rule 5: Layer-Based OrganizationEach layer should have:- Clear semantic meaning (User, Application, AI/Logic, Data, Infrastructure)- Consistent color coding- Grid-based layout for components- Appropriate nesting for sub-components ### Rule 6: Color SemanticsUse consistent semantic meaning for layers — the exact color palette varies by style (see examples). The standard semantic mapping:- **User Layer** — user-facing interfaces and clients- **Application Layer** — business logic and API services- **AI/Logic Layer** — intelligence, rules, processing engines- **Data Layer** — databases, caches, storage- **Infrastructure Layer** — containers, networking, DevOps- **External Services** — third-party APIs, cloud services (typically dashed border) ## Style Examples Choose a visual style that matches your project's tone and audience. Each example contains a complete, copy-ready HTML template. | # | Style | File | Suitable For ||---|---|---|---|| 1 | **Steel Blue** | [styles/steel-blue.md](styles/steel-blue.md) | Consulting reports, banking/finance, government projects, RFP proposals || 2 | **Ember Warm** | [styles/ember-warm.md](styles/ember-warm.md) | Retail/e-commerce, education platforms, lifestyle brands, cultural institutions || 3 | **Neon Dark** | [styles/neon-dark.md](styles/neon-dark.md) | Tech talks, developer conferences, gaming platforms, cybersecurity dashboards || 4 | **Stark Block** | [styles/stark-block.md](styles/stark-block.md) | Creative studios, education platforms, indie developers, tech blogs || 5 | **Ocean Teal** | [styles/ocean-teal.md](styles/ocean-teal.md) | Travel platforms, logistics/shipping, green tech, weather/ocean projects || 6 | **Dusk Glow** | [styles/dusk-glow.md](styles/dusk-glow.md) | Social media, entertainment platforms, martech, content creation tools || 7 | **Rose Bloom** | [styles/rose-bloom.md](styles/rose-bloom.md) | Fashion/beauty, luxury brands, wedding platforms, premium memberships || 8 | **Sage Forest** | [styles/sage-forest.md](styles/sage-forest.md) | Healthcare, agritech, clean energy, sustainability, bioinformatics || 9 | **Frost Clean** | [styles/frost-clean.md](styles/frost-clean.md) | Design tools, developer docs, API references, minimalist SaaS || 10 | **Indigo Deep** | [styles/indigo-deep.md](styles/indigo-deep.md) | Brand-consistent systems, enterprise white papers, internal platforms || 11 | **Pastel Mix** | [styles/pastel-mix.md](styles/pastel-mix.md) | SaaS products, startups, general tech architecture, product docs || 12 | **Slate Dark** | [styles/slate-dark.md](styles/slate-dark.md) | Enterprise dark mode, internal tools, developer dashboards | ## Layout Examples Choose a layout structure that fits your architecture's complexity.

Do NOT use `<line>`, Bézier curves, or diagonal lines.** See [layouts/connectors.md](layouts/connectors.md) for full reference. ```html<!-- Wrap diagram content in a relative container --><div style="position: relative;">  <!-- ...layers and components here... -->  <!-- SVG overlay as last child -->  <svg style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; pointer-events: none; overflow: visible;">    <defs>      <marker id="arrowhead" markerWidth="8" markerHeight="6" refX="8" refY="3" orient="auto">        <path d="M0,0 L8,3 L0,6" fill="none" stroke="#94a3b8" stroke-width="1"/>      </marker>    </defs>    <!-- Orthogonal solid arrow (vertical → horizontal → vertical) -->    <path d="M 200,72 L 200,90 L 400,90 L 400,108" class="arch-conn" marker-end="url(#arrowhead)"/>    <!-- Orthogonal dashed line -->    <path d="M 600,72 L 600,90 L 600,90 L 600,108" class="arch-conn-dashed" marker-end="url(#arrowhead)"/>    <!-- Label -->    <text x="420" y="86" class="arch-conn-label">data flow</text>  </svg></div>``` ## Styling Reference ### Common Classes (shared across all styles)- `.arch-wrapper` — flex container for sidebar + main layout- `.arch-sidebar` — fixed-width sidebar column- `.arch-main` — flexible main content area- `.arch-layer` — layer container (add semantic class: `.user`, `.application`, `.ai`, `.data`, `.infra`, `.external`)- `.arch-box` — component box; `.arch-box.highlight` for key items; `.arch-box.tech` for smaller tech items- `.arch-grid-2` to `.arch-grid-6` — grid column layouts- `.arch-sidebar-panel` — sidebar panel container- `.arch-sidebar-item` — sidebar item; `.arch-sidebar-item.metric` for highlighted metrics ## Best Practices ### HTML Usage Guidelines 1. **Direct embedding only** — Always embed HTML directly in Markdown, never use ` ```html ` code blocks2. **No empty lines in structure** — Keep the entire HTML block continuous without any empty lines3. **Incremental development** — Build diagrams step by step:   - Start with basic framework and layout structure (single/two/three column as needed)   - Add empty layer containers with proper CSS classes   - Fill in content layer by layer from top to bottom   - Refine content and add highlights last ### Architecture Design 1. **Keep layers logically separated** — Each layer should represent a clear architectural tier2. **Use consistent naming** — Follow naming conventions for components and services3. **Highlight key components** — Use `.highlight` class for critical components4. **Add technical details** — Include technology stack info in `<small>` tags5. **Balance information density** — Don't overcrowd components with text6. **Use icons sparingly** — Add emojis to titles for visual hierarchy7. **Maintain color semantics** — Stick to the established color meanings8. **Consider responsive design** — Grids automatically adapt to content
