Stylish Jupyter Notebook with jupyter-themes

Appearance of Jupyter Notebook can be modified using jupyter-themes.

See the following websites for details,

Chrome extension Stylish should be installed in addition to jupyter-themes.

My current setting is provided by the following command.

$ jt -t grade3 -f code -fs 12 -cellw 95% -lineh 140 -T -N -tf droidsans -tfs 12 -nf ptsans -nfs 12 -ofs 10

It looks good ;)
