# Gradient Mesh

> A rolling surface drawn in lines, shaded by depth.

Lines fade from faint at the back to strong at the front, so it reads as depth without colour: terrain, sound, a calm sea. Optional full wireframe.

- Family: Backgrounds
- Plan: Creative. Included with Creative.
- Requires: React, Tailwind CSS v4 and the motion package
- Page with a live preview: https://galactrex.com/ui/gradient-mesh/

## Install

```sh
npx @galactrex/ui login   # once, with an API key from https://galactrex.com/account/

```

It installs to `components/galactrex/gradient-mesh.tsx`, with the shared motion helpers beside it. First time in a project: `npx @galactrex/ui init` (setup guide: https://galactrex.com/docs/ui-components-setup/).

## Usage

```tsx
import { GradientMesh } from "@/components/galactrex/gradient-mesh";

<section className="relative overflow-hidden">
  <GradientMesh />
  <h1 className="relative">Signal</h1>
</section>
```
