index.html

It seems like you're asking for an HTML application, but you mentioned "its not html" which is a bit confusing. Could you clarify what you're looking for? Are you requesting a non-HTML application (like a desktop or mobile app) or is there a specific feature/functionality you'd like in an HTML-based web application?

If you're looking for a web application, I can create a modern, responsive HTML/CSS/JavaScript application for you. Please provide more details about:
1. The purpose of the application
2. Key features you'd like
3. Any specific design preferences
4. Whether you need any particular functionality (like forms, animations, data processing, etc.)

For example, I could create:
- A dashboard interface
- A portfolio website
- An interactive game
- A data visualization tool
- A productivity app
- Or something completely custom

Please provide more details so I can create exactly what you're looking for!
