Banner Design - Multi-Format Creative Banner System
Design banners across social, ads, web, and print formats. Generates multiple art direction options per request with AI-powered visual elements. This skill handles banner design only. Does NOT handle video editing, full website design, or print production.
When to Activate
- User requests banner, cover, or header design
- Social media cover/header creation
- Ad banner or display ad design
- Website hero section visual design
- Event/print banner design
- Creative asset generation for campaigns
Prerequisites
Python: This skill uses Python scripts. On Windows, use python instead of python3 (e.g., python scripts/search.py instead of python3 scripts/search.py).
Workflow
Step 1: Gather Requirements (AskUserQuestion)
Collect via AskUserQuestion:
- Purpose — social cover, ad banner, website hero, print, or creative asset?
- Platform/size — which platform or custom dimensions?
- Content — headline, subtext, CTA, logo placement?
- Brand — existing brand guidelines? (check
docs/brand-guidelines.md)
- Style preference — any art direction? (show style options if unsure)
- Quantity — how many options to generate? (default: 3)
Step 2: Research & Art Direction
- Activate
ui-ux-pro-max skill for design intelligence
- Use Chrome browser to research Pinterest for design references:
Navigate to pinterest.com → search "[purpose] banner design [style]"
Screenshot 3-5 reference pins for art direction inspiration
- Select 2-3 complementary art direction styles from references:
references/banner-sizes-and-styles.md
Step 3: Design & Generate Options
For each art direction option:
Create HTML/CSS banner using frontend-design skill
- Use exact platform dimensions from size reference
- Apply safe zone rules (critical content in central 70-80%)
- Max 2 typefaces, single CTA, 4.5:1 contrast ratio
- Inject brand context via
inject-brand-context.cjs
Generate visual elements with ai-artist + ai-multimodal skills
a) Search prompt inspiration (6000+ examples in ai-artist):
python3 .claude/skills/ai-artist/scripts/search.py "<banner style keywords>"
b) Generate with Standard model (fast, good for backgrounds/patterns):
.claude/skills/.venv/bin/python3 .claude/skills/ai-multimodal/scripts/gemini_batch_process.py \
--task generate --model gemini-2.5-flash-image \
--prompt "<banner visual prompt>" --aspect-ratio <platform-ratio> \
--size 2K --output assets/banners/
c) Generate with Pro model (4K, complex illustrations/hero visuals):
.claude/skills/.venv/bin/python3 .claude/skills/ai-multimodal/scripts/gemini_batch_process.py \
--task generate --model gemini-3-pro-image-preview \
--prompt "<creative banner prompt>" --aspect-ratio <platform-ratio> \
--size 4K --output assets/banners/
When to use which model:
| Use Case |
Model |
Quality |
| Backgrounds, gradients, patterns |
Standard (Flash) |
2K, fast |
| Hero illustrations, product shots |
Pro |
4K, detailed |
| Photorealistic scenes, complex art |
Pro |
4K, best quality |
| Quick iterations, A/B variants |
Standard (Flash) |
2K, fast |
Aspect ratios: 1:1, 16:9, 9:16, 3:4, 4:3, 2:3, 3:2
Match to platform - e.g., Twitter header = 3:1 (use 3:2 closest), Instagram story = 9:16
Pro model prompt tips (see ai-artist references/nano-banana-pro-examples.md):
- Be descriptive: style, lighting, mood, composition, color palette
- Include art direction: "minimalist flat design", "cyberpunk neon", "editorial photography"
- Specify no-text: "no text, no letters, no words" (text overlaid in HTML step)
Compose final banner — overlay text, CTA, logo on generated visual in HTML/CSS
Step 4: Export Banners to Images
After designing HTML banners, export each to PNG using chrome-devtools skill:
- Serve HTML files via local server (python http.server or similar)
- Screenshot each banner at exact platform dimensions:
# Export banner to PNG at exact dimensions
node .claude/skills/chrome-devtools/scripts/screenshot.js \
--url "http://localhost:8765/banner-01-minimalist.html" \
--width 1500 --height 500 \
--output "assets/banners/{campaign}/{variant}-{size}.png"
- Auto-compress if >5MB (Sharp compression built-in):
# With custom max size threshold
node .claude/skills/chrome-devtools/scripts/screenshot.js \
--url "http://localhost:8765/banner-02-gradient.html" \
--width 1500 --height 500 --max-size 3 \
--output "assets/banners/{campaign}/{variant}-{size}.png"
Output path convention (per assets-organizing skill):
assets/banners/{campaign}/
├── minimalist-1500x500.png
├── gradient-1500x500.png
├── bold-type-1500x500.png
├── minimalist-1080x1080.png # if multi-size requested
└── ...
- Use kebab-case for filenames:
{style}-{width}x{height}.{ext}
- Date prefix for time-sensitive campaigns:
{YYMMDD}-{style}-{size}.png
- Campaign folder groups all variants together
Step 5: Present Options & Iterate
Present all exported images side-by-side. For each option show:
- Art direction style name
- Exported PNG preview (use
ai-multimodal skill to display if needed)
- Key design rationale
- File path & dimensions
Iterate based on user feedback until approved.

Design Rules
- Safe zones: critical content in central 70-80% of canvas
- CTA: one per banner, bottom-right, min 44px height, action verb
- Typography: max 2 fonts, min 16px body, ≥32px headline
- Text ratio: under 20% for ads (Meta penalizes heavy text)
- Print: 300 DPI, CMYK, 3-5mm bleed
- Brand: always inject via
