The provided code is generally clear, but there are some minor improvements and potential adjustments to consider:

### Potential Improvements:
1. **Consistent Naming Convention**: Ensure consistent use of capitalization (e.g., `qustion-content` should be `question-content`) across the template tags.

2. **CSS Flexbox Layout**: The existing flexbox layout does not require changing properties that might need adjustment depending on specific usage context or future changes in design requirements.

3. **Functionality Verification**: Ensure that the `downloadFile` function and its logic (`onMounted`) work correctly within the application's context.

4. **Whitespace Consistency**: Minor whitespace inconsistencies could be improved for better readability (though they are already fairly uniform).

5. **Accessibility Considerations**: If this component handles user interactions or content presentation, ensure it adheres to accessibility guidelines, such as providing appropriate ARIA roles and attributes where needed.

### Suggestions:
1. **Naming Consistency**:

-qustion-content

2. **Flexbox Property Adjustments**:
- Since the current properties (`display: flex`, `justify-content: flex-end`) seem appropriate given the context, no major changes are needed here unless additional styling requirements arise later on.

3. **Functionality Testing**:
- Add detailed test cases if testing functions like `downloadFile` to ensure all edge cases are handled properly.

4. **Whitespace Formatting**:
- Continue maintaining consistent indentation to enhance readability.

5. **Accessibility Checks**:
- Review the HTML structure to confirm that elements have appropriate role and aria-labels if necessary.

These points cover general maintenance considerations and may require further customization based on broader project needs and development practices.
