On June 4, 2025, at 1:51 PM AEST, I embarked on an exhilarating mission to transform a mundane T3 App landing page into a dazzling Tailwind CSS Feature Demo that would showcase the full might of Tailwind CSS v4. Using Cursor, Context7 MCP, and Claude Sonnet 4, I collaborated with AI to create a repository that’s not just a demo but a testament to modern web development. The result, hosted at github.com/mingfangdev/context7-example, is a stunning collection of 3D transforms, advanced gradients, and interactive animations. This blog post dives deep into every prompt I gave, every response Cursor delivered, and how we turned a simple idea into a tutorial-ready masterpiece. Inspired by mingfang.tech/harnessing-context7-mcp/, this is the story of our journey and how you can replicate it.
The Vision: A Showcase of Tailwind’s Cutting-Edge Features
My goal was ambitious: take a basic T3 App page and rebuild it as a Tailwind CSS feature demo with three complex examples that highlight the framework’s most advanced capabilities. I wanted to push Tailwind CSS v4 to its limits, showcasing 3D effects, modern gradients, and dynamic animations, all while leveraging AI tools to make the process fast, precise, and educational. The end product needed to be a learning resource, documented thoroughly for others to follow, much like a tutorial.
I turned to Cursor, an AI-powered IDE that integrates Context7 MCP for real-time documentation access and Claude Sonnet 4 as my pair-programming partner. This setup promised to blend human creativity with AI efficiency, making the impossible possible in record time.

This stack, paired with an AI-human pair programming approach, enabled us to iterate rapidly, tackle challenges, and produce a polished repository now live at github.com/mingfangdev/context7-example.
The Journey: From Prompt to Polished Repository
The steps below is what the Cursor do with Agent mode.
Step 1: The Initial Prompt
I opened Cursor and typed my first prompt, filled with excitement:
“help me rebuild the page in a tailwind css feature demo page. and make 3 complex example that show the capability of tailwind css.”
Cursor, powered by Claude Sonnet 4, responded instantly with a comprehensive plan. It proposed transforming the T3 App’s basic landing page into a feature-rich demo with three showcase sections:
- 3D Transform Gallery: Interactive cards with 3D flips, floating animations, and shape morphing.
- Advanced Gradient System: Conic, radial, and angled gradients with color interpolation modes.
- Interactive Animation Playground: Complex keyframe animations with staggered effects.
Using Context7 MCP, the AI queried Tailwind’s documentation to ensure we leveraged v4’s latest features:
resolve-library-id -> "tailwindcss"
get-library-docs -> "/tailwindlabs/tailwindcss.com"
This gave us access to utilities like transform-3d, bg-conic, and [animation-delay:-0.3s]. Cursor’s response included a complete page.tsx file, restructuring the page with a modern design:
Cursor’s Output (page.tsx Snippet):
import Link from "next/link";
export default function HomePage() {
return (
<main className="min-h-screen bg-gradient-to-br from-slate-900 via-purple-900 to-slate-900">
<div className="relative px-6 py-24 mx-auto max-w-7xl lg:px-8">
<h1 className="text-4xl font-bold tracking-tight text-white sm:text-6xl lg:text-7xl">
<span className="bg-gradient-to-r from-cyan-400 via-purple-400 to-pink-400 bg-clip-text text-transparent">

<br />
<span className="text-white/90">Feature Demo</span>
</h1>
<p className="mt-6 text-lg leading-8 text-gray-300 max-w-2xl mx-auto">

3D transforms, complex animations, gradient interpolation, and cutting-edge utilities.
</p>
</div>
{/* Example sections to follow */}
</main>
);
}
This output was a revelation. The AI had taken my broad request and delivered a sleek, gradient-backed hero section with gradient text and a clear structure for the demo. I was ready to build the examples.
(Agent)Step 2: Building the 3D Transform Gallery
The Agent start to do the coding —a gallery of 3D effects that would captivate users. Cursor responded with a section featuring three interactive cards:
- 3D Card Flip: A card that rotates 180 degrees on hover to reveal a back side.
- Floating Animation: A card that hovers and scales with a custom keyframe animation.
- Morphing Shape: A card that transforms from a rectangle to a circle on hover.
Cursor’s Output (3D Gallery Snippet):
<section className="space-y-8">
<h2 className="text-3xl font-bold text-white mb-4">3D Transform Gallery</h2>
<div className="perspective-[1000px] grid grid-cols-1 md:grid-cols-3 gap-8">
<div className="group relative h-64 transform-3d transition-transform duration-700 hover:rotate-y-180">
<div className="absolute inset-0 w-full h-full rounded-xl bg-gradient-to-br from-blue-500 to-purple-600 shadow-2xl backface-hidden">
<div className="p-6 h-full flex flex-col justify-center items-center text-white">
<h3 className="text-xl font-bold">3D Rotation</h3>
<p className="text-center text-sm opacity-90">Hover to flip</p>
</div>
</div>
<div className="absolute inset-0 w-full h-full rounded-xl bg-gradient-to-br from-pink-500 to-orange-500 shadow-2xl backface-hidden rotate-y-180">
<div className="p-6 h-full flex flex-col justify-center items-center text-white">
<h3 className="text-xl font-bold">Back Side</h3>
<p className="text-center text-sm opacity-90">3D transforms in action!</p>
</div>
</div>
</div>
{/* Floating and morphing cards followed */}
</div>
</section>
The AI used perspective-[1000px] for realistic 3D depth, transform-3d for hardware-accelerated transforms, and backface-hidden for clean flips. However, the initial hover transitions were choppy. Cursor analyzed the issue and adjusted the transition-transform duration to 700ms, resulting in smooth, cinematic animations. This section became a highlight of the repo, showcasing Tailwind’s 3D capabilities.
(Agent)Step 3: Crafting the Advanced Gradient System
Next, the AI responded with a grid comparing different gradient types and interpolation modes:
- Conic Gradients: Circular gradients with
bg-conicandbg-conic-180. - Radial Gradients: Positioned gradients with
bg-radial-[at_25%_25%]. - Color Interpolation: Visual comparisons of
srgb,hsl,oklab, andoklchmodes. - Angled Gradients: Diagonal gradients with
bg-linear-45andbg-linear-135.
Cursor’s Output (Gradient System Snippet):
<section className="space-y-8">
<h2 className="text-3xl font-bold text-white mb-4">Advanced Gradient System</h2>
<div className="grid grid-cols-1 lg:grid-cols-2 gap-8">
<div className="space-y-6">
<h3 className="text-xl font-semibold text-white">Conic Gradients</h3>
<div className="grid grid-cols-3 gap-4">
<div className="aspect-square rounded-full bg-conic from-blue-600 to-sky-400 to-50% shadow-lg"></div>
<div className="aspect-square rounded-full bg-conic-180 from-indigo-600 via-indigo-50 to-indigo-600 shadow-lg"></div>
<div className="aspect-square rounded-full bg-conic/decreasing from-violet-700 via-lime-300 to-violet-700 shadow-lg"></div>
</div>
</div>
<div className="space-y-6">
<h3 className="text-xl font-semibold text-white">Color Interpolation Modes</h3>
<div className="flex items-center gap-4">
<span className="text-sm font-mono text-gray-400 w-16">oklch</span>
<div className="flex-1 h-8 rounded bg-linear-to-r/oklch from-indigo-500 to-teal-400"></div>
</div>
{/* Other modes followed */}
</div>
</div>
</section>
Context7 MCP was invaluable here, providing precise v4 syntax for gradients. The AI cross-referenced Tailwind’s documentation to ensure accuracy, making this section a visual and technical triumph. The interpolation mode comparison was particularly eye-opening, showing how oklch produces smoother color transitions than srgb.
(Agent)Step 4: Creating the Interactive Animation Playground
Agent give an animation playground to showcase Tailwind’s dynamic capabilities. Cursor delivered a grid with four components:
- Bouncing Loader: Three dots with staggered
animate-bounceeffects. - Multi-Speed Rotation: Spinners with varying
animation-duration. - Pulsing Hearts: Heart emojis with timed
animate-pulseeffects. - Interactive Showcase: A card combining multiple hover animations.
Cursor’s Output (Animation Playground Snippet):
<section className="space-y-8">
<h2 className="text-3xl font-bold text-white mb-4">Interactive Animation Playground</h2>
<div className="grid grid-cols-1 lg:grid-cols-3 gap-8">
<div className="bg-white/5 backdrop-blur-sm rounded-xl p-8 border border-white/10">
<h3 className="text-lg font-semibold text-white mb-6 text-center">Bouncing Loader</h3>
<div className="flex justify-center items-center space-x-2">
<div className="w-4 h-4 bg-blue-500 rounded-full animate-bounce [animation-delay:-0.3s]"></div>
<div className="w-4 h-4 bg-purple-500 rounded-full animate-bounce [animation-delay:-0.15s]"></div>
<div className="w-4 h-4 bg-pink-500 rounded-full animate-bounce"></div>
</div>
</div>
{/* Other animations followed */}
</div>
</section>
Agent found the issue and it needed a custom floating animation for one card, but the initial attempt using styled-jsx caused parsing errors. Cursor suggested moving to a global globals.css file:
Cursor’s Output (globals.css):
@import "tailwindcss";
@keyframes float {
0%, 100% { transform: translateY(0px); }
50% { transform: translateY(-10px); }
}
.animate-spin-slow {
animation: spin 3s linear infinite;
}
.animate-float {
animation: float 6s ease-in-out infinite;
}
This fixed the issue, and the animations ran smoothly, adding a playful yet professional touch to the repo.
(Agent)Step 5: Overcoming Challenges
Our journey had its share of challenges, but Cursor’s real-time problem-solving kept us on track then Agent start to debug:
- JSX Syntax Error: An apostrophe in “Tailwind’s” broke the linter. Cursor flagged the issue:
Line 20: `'` can be escaped with `'`We replaced it with', resolving the error instantly. - Tailwind v4 Migration: The AI initially used v3 syntax:
@tailwind base; @tailwind components; @tailwind utilities;Context7 MCP revealed v4’s new syntax:@import "tailwindcss";We updatedglobals.css, ensuring compatibility. - Background Pattern Issue: A complex SVG background caused rendering issues. Cursor simplified it:
<div className="absolute inset-0 bg-gradient-to-br from-white/5 to-transparent opacity-20"></div> - Styled-JSX Incompatibility: The
styled-jsxapproach for custom animations failed. Cursor proposed a global CSS file, which worked flawlessly.
Each challenge was documented, turning obstacles into learning opportunities for the tutorial.
Step 6: Documenting for the Community
With the demo complete, I wanted to share our process as a tutorial. I prompted Cursor:
“help me summary about our conversation and put in a md file.”
Cursor generated a markdown file summarizing our collaboration, code snippets, and lessons learned. I realized I needed more detail for a tutorial, so I refined my prompt:
“Is that include how we made likle the logic how we chat I want to include all of those. Later I will use it for tutorial show people how to do it. The key tech stack have to be mentioned on thje top mcp that we use is also”
Cursor responded with an expanded tutorial, including our exact prompts, responses, MCP workflows, and the tech stack. This became the foundation for the repo’s documentation and this blog post.
Cursor’s Output (Markdown Snippet):
