Adjust the cell width of the Jupyter notebook

The default width of the notebook cell is sometimes not fit the purpose to display the content. In this case, we would like to adjust the cell size. There are few solutions to do this.

The permanent solution is to create a file in the home folder for IPython notebook.

~/.ipython/profile_default/static/custom/custom.css

or Jupyter notebook

~/.jupyter/custom/custom.css

with content

.container { width:100% !important; }

Then restart iPython/Jupyter notebooks. Note that this will affect all notebooks. 

If you don't want to change your default settings, and you only want to change the width of the current notebook you're working on, you can enter the following into a cell:

from IPython.core.display import display, HTML
display(HTML("<style>.container {width:90% !important;</style>"))
