Fixes and Improvements:

#10: Fix issue on mobile where some documentation pages become wider than the screen

• The issue seems to arise only on localhost and works perfectly on GitHub pages. This issue is likely due to how localhost renders LaTeX expressions. Safe to say this can be ignored.

#9: Add dark mode to docs

• Added dark mode to the documentation page by updating the layout and global CSS files.
• Introduced a new dark mode theme in the global CSS file.
• Configured Tailwind CSS to support dark mode by modifying the tailwind.config.cjs file to enable class-based dark mode.

#7: Add unit testing

• Added multiple unit testing cases to cover various components and functionalities of the project.
• The test files include:
  • test_base.py
  • test_data.py
  • test_distribution.py
  • test_guidance.py
  • test_loss.py
  • test_model.py
  • test_net.py
  • test_noise.py
  • test_schedule.py
  • test_time.py

#4: Add text generation guide

• Added a new guide for text generation using the same markdown format as other documentation pages.

#3: Add image generation guide

• Added a new guide for image generation using the same markdown format as other documentation pages.
