The AI prompt

Paste this into an AI coding tool to generate the same background, then ask it to adapt the colours, text or framework to your project.

Works with Claude · ChatGPT · Cursor · v0 · Bolt · Gemini
Create a cyber printed circuit board (PCB) background in pure HTML and CSS.

Requirements:
- Dark emerald solder mask backdrop (#020b08).
- Orthogonal grid traces created with linear-gradient and radial-gradient solder pads.
- Vignette overlay ensuring center readability.
- Zero JavaScript.

Return one HTML file with a <style> block.

How to build it, step by step

  1. 1

    Combine two linear gradients and two offset radial gradients to form circuit paths with junction solder pads.

  2. 2

    Add radial vignette to fade peripheral traces into the shadows.

Customisation tips

  • Set background-size: 40px 40px to keep trace density tight and sharp.
