Readability counts. —The Zen of Python, by Tim Peters

Chesterish theme for Jupyter Notebook is beautiful. However when you need some large font, everything start to fail apart.

So here is a modified Chesterish theme featuring:

• Dark theme
• Large font (16pt) to make your eye happier
• Everything perfectly aligned
• Use your OS native UI font as Jupyter UI font
• Use Iosevka webfont as monospace font

Note:

• Tested under Chrome (most recent stable) on Windows and Safari on macOS.
• If you installed Sarasa Gothic on your computer, it will be used instead of Iosevka. It is recommended if you need CJK font in your Jupyter notebook.

Put the theme under your Jupyter personal config folder (default location is ~/.jupyter/custom).

git clone https://github.com/Jamesits/jupyter-theme-chesterish-paranoid.git ~/.jupyter/custom

Then restart Jupyter server. (JupyterHub user can restart their own server from URL /hub/home.)
