Very nice...but warning, it may require some effort to go back to default theme (see https://github.com/dunovank/jupyter-themes/issues/86 )

I can't actually recommend it until this is fixed.

The only step needed there was ctrl-F5. Browser caching can be annoying. I'm not sure that it is up to the jupyter devs to fix it though?

I was wondering how in the http://fast.ai lectures how they got juypter to look like that. Apparently they used this. Makes notebooks look really slick.

that was the first thing that popped in my mind when i saw those notebooks too... so much nicer looking than what I was working with.

I have long wanted to use a dark theme for Jupyter. This works great for my needs.

These look very nice. Cannot wait to see what other designs people come up with.

All I want is to hide the toolbar by default. Wastes several clicks and a few seconds of setup time every time I give a talk from a notebook.

Put this in .jupyter/custom/custom.js

  require(['base/js/namespace', 'jquery'], function(IPython, $) {
    $([IPython.events]).on('notebook_loaded.Notebook',   function() {
      $('#header-container').hide();
      $('.header-bar').hide();
      $('div#maintoolbar').hide();
      IPython.menubar._size_header();
    });
  });

I've been using this for a while and love it. Just wish there were more template themes.

Always looking for user-submitted themes :) Feel free to submit a pull-request with anything cool you come up with.

thanks for the positive feedback y'all!

I am using it for sometime now. Love it!
