How do I increase the cell width of the Jupyter/ipython notebook in my browser?

I would like to increase the width of the ipython notebook in my browser. I have a high-resolution screen, and I would like to expand the cell width/size to make use of this extra space.


edit: 5/2017

I now use jupyterthemes:

and this command:

    jt -t oceans16 -f roboto -fs 12 -cellw 100%

which sets the width to 100% with a nice theme.

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:100% !important; }</style>"))
