Does this skill require external image assets?

No, it can generate its own backgrounds and mockups using Gemini 3.1 Flash prompt patterns, though it can also wrap your existing local screenshots in CSS frames.

Can I apply my own brand colors to the mockups?

Absolutely. The skill is designed to read from a .agents/design-context.md file to automatically apply your brand's specific color palette and typography.

What kind of 3D effects are supported?

The skill includes snippets for isometric views, floating perspective animations, stacked multi-device layouts, and 3D CSS packaging boxes.

Are the CSS device frames responsive?

Yes, the provided CSS templates use modern layout techniques like Flexbox and Aspect Ratio to ensure mockups scale properly across different screen sizes.
