Rapid UI Design with Antigravity + Skills: A Complete Guide from Idea to Deployment

Want to go from idea to live UI in just a few hours? This article will teach you how to use Antigravity and Skills packages to rapidly build professional, usable, and reusable page designs with AI assistance. Whether it’s a product landing page, marketing page, or admin dashboard, you’ll find an efficient path to realization here.

What are Antigravity and Skills?

Antigravity is an AI-driven page generation tool that understands natural language requirements and automatically generates corresponding UI code and design drafts. Unlike traditional template tools, Antigravity builds pages through semantic understanding rather than simply applying fixed templates.

Skills is a modular capability system where each Skill encapsulates design knowledge and best practices for specific domains. For example:

• UI/UX Pro Max Skill: Professional-grade page design standards
• Component Library Skill: Common component library integration
• Responsive Design Skill: Responsive layout optimization

Combining the two, you can:

• Describe requirements in natural language, and AI generates the initial design
• Invoke professional Skills to optimize details (color schemes, spacing, components)
• Iterate quickly, completing the process from idea to launch in a few hours

Environment Preparation and Quick Start

Prerequisites

• Node.js 18+ or Bun Runtime
• Basic frontend knowledge (HTML/CSS)
• (Optional) Installed OpenCode or Claude Code

Install Antigravity CLI

# Install using npm
npm install -g antigravity-cli

# Or using bun (faster)
bun add -g antigravity-cli

# Verify installation
antigravity --version

Initialize Project

# Create new project
antigravity init my-landing-page

# Enter project directory
cd my-landing-page

# Start dev server
antigravity dev

At this point, the browser will automatically open http://localhost:3000, showing a blank canvas waiting for your creative input.

Complete Hands-on Case 1: Building a Product Landing Page

Let’s demonstrate the full process from requirements to launch with a real-world case.

Scenario Requirement

Suppose you want to create a landing page for an AI writing tool, targeting content creators and marketers.

Step 2: Generate Initial Version and Preview

After clicking “Generate”, Antigravity will produce the complete page code (HTML + Tailwind CSS) within about 30 seconds.

Generation Result Example (Partial Code):

<!-- Hero Section -->
<section class="relative bg-gradient-to-r from-purple-600 to-blue-500 text-white py-20">
  <div class="container mx-auto px-6 text-center">
    <h1 class="text-5xl font-bold mb-4">
      Boost Writing Efficiency 10x with AI Assistant
    </h1>
    <p class="text-xl mb-8 opacity-90">
      Helping content creators rapidly generate high-quality articles, copy, and ideas
    </p>
    <div class="flex gap-4 justify-center">
      <button class="bg-white text-purple-600 px-8 py-3 rounded-lg font-semibold hover:bg-gray-100">
        Free Trial
      </button>
      <button class="border-2 border-white px-8 py-3 rounded-lg font-semibold hover:bg-white/10">
        Watch Demo
      </button>
    </div>
  </div>
</section>

<!-- Features Section -->
<section class="py-16 bg-gray-50">
  <div class="container mx-auto px-6">
    <div class="grid md:grid-cols-3 gap-8">
      <!-- Feature 1 -->
      <div class="bg-white p-8 rounded-xl shadow-sm">
        <div class="w-12 h-12 bg-purple-100 rounded-lg flex items-center justify-center mb-4">
          <svg class="w-6 h-6 text-purple-600">...</svg>
        </div>
        <h3 class="text-xl font-semibold mb-2">Smart Continuation</h3>
        <p class="text-gray-600">One-click content generation, say goodbye to writer's block</p>
      </div>
      <!-- Feature 2, 3... -->
    </div>
  </div>
</section>

Step 3: Apply Skills Optimization

Now call professional Skills for optimization:

# Enter in Antigravity console
/apply-skill ui-ux-pro-max

# Skills will automatically optimize:
# - Adjust spacing to fit 8px grid system
# - Optimize contrast to meet WCAG AA standards
# - Add micro-interaction animations
# - Unify shadow and radius styles

Comparison Before and After Optimization:

Step 4: Replace with Real Content

The generated page has a complete structure. Now replace placeholders with real content:

1. Replace Copy: Modify titles, description text
2. Upload Images: Replace placeholders with real product screenshots
3. Update Links: Set CTA button redirect URLs
4. Configure FAQ: Fill in actual common questions

Step 5: Responsive Adjustment

# Test mobile adaptation
antigravity preview --device mobile

# If issues found, use Responsive Skill
/apply-skill responsive-design --breakpoint mobile

Step 6: Export and Deploy

# Export static files
antigravity build

# Generated files are in dist/ directory
# Can be directly deployed to Vercel, Netlify, or any static hosting service

Final Outcome:

• Development Time: Approx 2-3 hours (including content prep)
• Code Volume: Approx 500 lines (1500+ lines if handwritten)
• Page Performance: Lighthouse Score 95+

Complete Hands-on Case 2: Admin Dashboard Design

Scenario Requirement

Build a data analysis dashboard including charts, tables, filters, and other complex components.

Key Prompts

Create a data analysis dashboard containing:

Layout:
- Fixed left navigation bar (width 240px)
- Top title bar (height 64px)
- Main content area responsive layout

Core Modules:
1. Statistic Cards Area (4 metric cards)
   - Total Users, Active Users, Conversion Rate, Revenue
   - Each card displays trend chart (Up/Down)

2. Charts Area (2 rows 2 columns)
   - Line Chart: User growth past 7 days
   - Pie Chart: User source distribution
   - Bar Chart: Feature usage frequency
   - Heatmap: Active time distribution

3. Data Table
   - Supports sorting, filtering, pagination
   - Displays last 100 user behavior records

Color Scheme: Dark mode, primary color #3B82F6 (Blue), background #1F2937
Component Library: Use shadcn/ui

Special Trick: Invoke Component Library Skill

# Integrate shadcn/ui component library
/apply-skill component-library --library shadcn

# Antigravity will automatically:
# 1. Install necessary dependencies
# 2. Configure Tailwind CSS
# 3. Import required components (Table, Chart, Card, etc.)
# 4. Apply consistent style theme

Generated code will directly use professional components without manual configuration:

import { Card, CardContent, CardHeader, CardTitle } from "@/components/ui/card"
import { LineChart, Line, XAxis, YAxis, Tooltip } from "recharts"

export function Dashboard() {
  return (
    <div class="grid grid-cols-4 gap-6">
      <Card>
        <CardHeader>
          <CardTitle>Total Users</CardTitle>
        </CardHeader>
        <CardContent>
          <div class="text-3xl font-bold">12,584</div>
          <div class="text-green-500 text-sm">↑ 12.5% vs Last Week</div>
        </CardContent>
      </Card>
      {/* Other cards... */}
    </div>
  )
}

Core Workflow Summary

5-Step Efficient Process

1. Requirements Description (5-10 mins)
   ↓
   Write structured prompts, clarifying:
   - Page type (Landing/Admin/Blog)
   - Core modules (Hero/Features/Pricing)
   - Design style (Modern/Minimalist/Gradient)

2. AI Generation Initial Version (30s - 2 mins)
   ↓
   Antigravity automatically outputs complete code
   
3. Skills Professional Optimization (2-5 mins)
   ↓
   Apply ui-ux-pro-max, responsive-design skills
   
4. Content Replacement & Tweak (30 mins - 2 hours)
   ↓
   Replace copy, images, links
   
5. Test & Deploy (10-30 mins)
   ↓
   Multi-device testing → Export → Deploy

3 Core Principles

1. Content First, Design Second
   Good content (clear selling points, real cases) is more important than fancy design. Prepare copy and images before designing.

2. Restraint is Sophistication

   • Use only 1-2 primary colors
   • Use only 2-3 font sizes
   • Maintain ample whitespace
   • Avoid excessive decoration

3. Rapid Iteration, Data Validation
   Generate 2-3 versions, use A/B testing to find the optimal solution instead of pursuing “perfection at once”.

Troubleshooting and FAQ

Issue 1: Generated result is too “Template-like”

Symptom: Page looks like a template, lacking personality.

Solution:

1. Replace Hero Visuals: Change default images and colors, use brand colors
2. Modify Title Copy: Avoid template expressions like “We provide…”, use user perspective “You will get…”
3. Add Real Cases: User reviews, data screenshots, team photos
4. Adjust Details: Modify radius sizes (e.g., 8px → 12px), spacing ratios

Before Optimization:

<h1>Welcome to our product</h1>

After Optimization:

<h1>Complete Monthly Report in 3 Minutes, Say Goodbye to Overtime</h1>

Issue 2: Generated code doesn’t run

Symptom: Page shows errors after export.

Common Causes and Fixes:

Debugging Steps:

# 1. Check dependencies
npm install

# 2. Clear cache and rebuild
rm -rf .next node_modules
npm install
npm run dev

# 3. View detailed errors
npm run dev -- --verbose

Issue 3: Mobile display abnormality

Symptom: Layout messed up or content overflows on mobile.

Solution:

# Apply Responsive Skill auto-fix
/apply-skill responsive-design

# Or manually check these common issues:

Checklist:

• Is <meta name="viewport" content="width=device-width, initial-scale=1"> set?
• Added max-w-full to fixed-width containers?
• Added w-full h-auto to images?
• Table wrapped in overflow-x-auto container?
• Font size too small on mobile (min recommended 14px)?

Issue 4: Uncoordinated Color Scheme

Symptom: Generated color combination looks unprofessional.

Solution:

1. Use Palette Tools to Verify:

   • Coolors - Generate coordinated palettes
   • Contrast Checker - Check contrast

2. Apply 60-30-10 Rule:

   • 60% Primary (Background, Large areas)
   • 30% Secondary (Cards, Sections)
   • 10% Accent (Buttons, Links)

3. Use Antigravity Color Skill:

/apply-skill color-palette --brand-color "#8B5CF6" --mode light

Issue 5: Slow Generation Speed

Symptom: Waiting time exceeds 2 minutes.

Optimization:

1. Batch Generation: Generate core modules first, then add secondary parts
2. Simplify Prompts: Focus on top 3-5 sections
3. Use Local Model (Advanced):

antigravity install --local
antigravity dev --mode local
