Product mockup

Product Mockup Design

Create professional product mockups and showcases using pure HTML/CSS. Device frames, 3D perspective transforms, feature callouts, and presentation layouts.

---

Step 1: Load Design Context

1. Read .agents/design-context.md for brand colors, fonts, style
2. If missing, ask user to run design-context skill or use defaults
3. Product mockups should match the brand's design style (minimal, bold, luxurious, etc.)

Gemini 3.1 Flash Image Preview

For AI image generation, see the image-generation skill for the full Gemini pipeline. Below are domain-specific prompt patterns for this skill.

Example Prompts

• Product Photo: "Place this [product] on a [background description]. Professional product photography style. [lighting]. [additional elements]."
• Device Mockup: "Create a [device type] mockup showing [app/website screenshot]. [angle/perspective] view on a [surface/background]. Soft shadows, [lighting style]. Clean, realistic presentation."
• Packaging Mockup: "Create a product packaging mockup for [brand]. [box/bottle/bag] with [label design description] on a [background]. Studio lighting, [additional props]. Premium, shelf-ready look."

}
@keyframes gentleFloat {
  0%, 100% { transform: rotateY(-15deg) rotateX(5deg) translateZ(20px) translateY(0); }
  50% { transform: rotateY(-15deg) rotateX(5deg) translateZ(20px) translateY(-12px); }
}

  background: radial-gradient(ellipse at 50% 120%, rgba(var(--primary-rgb), 0.15) 0%, transparent 60%),
              linear-gradient(180deg, #0F172A 0%, #1E293B 100%);
}

Desk/Surface Scene

.desk-scene {
  position: relative; background: linear-gradient(180deg, #F8FAFC 0%, #E2E8F0 100%);
  min-height: 600px; display: flex; align-items: flex-end; justify-content: center; padding-bottom: 40px;
}
.desk-scene::before {
  content: ''; position: absolute; bottom: 0; left: 0; right: 0; height: 40%;
  background: linear-gradient(180deg, #E2E8F0, #CBD5E1);
}
.desk-scene .device { position: relative; z-index: 2; filter: drop-shadow(0 20px 40px rgba(0,0,0,0.15)); }

.comparison { position: relative; width: 800px; aspect-ratio: 16/9; overflow: hidden; border-radius: 12px; box-shadow: 0 20px 60px rgba(0,0,0,0.2); }
.comparison .before, .comparison .after { position: absolute; inset: 0; }
.comparison .before { z-index: 1; filter: grayscale(50%) brightness(0.9); }
.comparison .after  { z-index: 2; clip-path: inset(0 50% 0 0); }
.comparison .divider { position: absolute; left: 50%; top: 0; bottom: 0; width: 3px; background: #fff; z-index: 3; }

Quality Checklist

• Device frames look realistic (proper proportions, shadows, details)
• Shadows are natural (soft, directional, not uniform)
• 3D transforms have appropriate perspective depth
• Screenshot content is visible and not distorted
• Brand colors from design-context used for stage/background
• Multiple devices are properly scaled relative to each other
• The overall composition draws attention to the product
• Code is self-contained HTML/CSS
