I'll create a development learning platform UI with practical exercises, course navigation, and a coding environment. Let's build something visually appealing and functional!

I've created a comprehensive development learning platform UI with a focus on practical exercises. Here's what's included:

Main Pages:

1. Home Page - Showcases the platform's features with:

   • Hero section with call-to-action
   • Featured courses section
   • Interactive coding environment preview
   • Platform benefits

2. Courses Page - Browse and filter available courses:

   • Course cards with thumbnails and details
   • Category tabs for easy navigation
   • Search functionality

3. Course Detail Page - Comprehensive view of a specific course:

   • Course overview and curriculum
   • Progress tracking
   • Module and lesson structure
   • Resources and discussions tabs

4. Lesson Page - Interactive learning experience:

   • Video player with lesson content
   • Transcript for text-based learning
   • Practice exercises with code editor
   • Navigation between lessons

5. Practice Playground - Hands-on coding environment:

   • Live code editor with syntax highlighting
   • Console output for testing code
   • Coding challenges and practice projects
   • Multiple language support

Key Features:

• Responsive Design - Works on all screen sizes
• Interactive Code Editor - Practice coding directly in the browser
• Progress Tracking - Monitor your learning journey
• Structured Curriculum - Clear learning path from beginner to advanced
• Modern UI - Clean, professional design with shadcn/ui components

The platform provides a complete learning experience with both theoretical content and practical exercises, similar to popular platforms like CodeChef but with a modern, user-friendly interface.
