## Features Implemented:
1. **Drag & Drop Interface**: Users can drag HTML files or click to browse
2. **File Selection**: Shows the selected file name
3. **Conversion Options**:
- Page size (A4, Letter, Legal, A3)
- Orientation (Portrait, Landscape)
- Margin settings
4. **Conversion Process**:
- Shows progress bar
- Status messages
5. **Download Functionality**:
- Download button for the converted PDF
- Option to start a new conversion
6. **Responsive Design**: Works on different screen sizes
7. **Visual Feedback**: Color changes during drag-over and status updates
## Important Notes:
1. This is a frontend simulation. In a real implementation, you would need to:
- Use a library like jsPDF or html2pdf.js for actual conversion
- Or implement server-side conversion with a service
2. For Blogger, you might need to:
- Adjust some styling to match your theme
- Ensure any external libraries are properly loaded
3. The current implementation simulates the conversion process with a progress bar but doesn't actually convert HTML to PDF. For real conversion, you would need to integrate a proper library.
