Description
We could enable dark mode for our document to make it more user-friendly. This task includes:
- Add component to change mode
- Have light/dark mode responsive GitHub/Colab/BigDL logos
- Make tab components have suitable background in dark mode
- Restyle line number in code block in dark mode
- Check the whole doc in dark mode to make sure there is no place with strange looking
After enabling dark mode, more rules for document writing should also be added to make sure the newly-added page look good both in light and dark mode.
