The AI prompt

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

Create a full-screen linear CSS gradient background called "Emerald Night".

Requirements:
- A single div that fills the viewport (min-height: 100vh).
- Use this exact background value:
  linear-gradient(135deg, #022c22 0%, #065f46 55%, #34d399 100%)
- Colours used: #022c22, #065f46, #34d399.
- No images and no JavaScript.
- Also give me the same gradient as a Tailwind CSS arbitrary value class and as a CSS custom property (--gradient-emerald-night) I can reuse.

Return one HTML file with the CSS in a <style> tag.

How to build it, step by step

1. 1

   Create an element to hold the gradient and give it a size. A gradient is a background image, so an element with no height shows nothing.

2. 2

   Use linear-gradient(). The first value is the direction (an angle such as 135deg, or a keyword such as 'to top'); the rest are colour stops with optional positions.

3. 3

   Add the colour stops: #022c22 → #065f46 → #34d399. Where no position is given, the browser spaces the stops evenly.

4. 4

   Check text contrast. Place your real heading on top and make sure it stays readable across the whole gradient, not just in one corner.

Customisation tips

• Store the gradient in a CSS custom property so every section uses the same value.
• Use white or very light text on this gradient.
• Add a subtle noise texture on top (see the Film Grain background) to remove visible colour banding on large screens.
