it [seem to me](http://www.w3schools.com/cssref/sel_link.asp) that link is only a subcategory on link. Deployed on [nbviewer](http://gistpynb.herokuapp.com/url/jakevdp.github.com/downloads/notebooks/XKCD_plots.ipynb) it does not remove the styling...but it might be a combine effect with the fact that the anchor tag do not have href attributes.
