Seeking (hopefully simple) HTML design help

Hi all,

We'd like to make a much better 404 page for our docs. Basically: incorporate the logo, include the Google site search, and have minimally pleasant visual design. It's this last part that is the problem for the currently active core devs. :slight_smile: If you are interested in making a useful contribution to an OSS project, now is your chance! In which case please feel free to chime in on this issue:

Somewhat related it would also be nice to create a simple 403 page for the Bokeh server to display as well.
