    Buttondown
    A Markdown/MultiMarkdown/Pandoc HTML output CSS stylesheet
    Author: Ryan Gray
    Date: 15 Feb 2011
    Revised: 21 Feb 2012

    General style is clean, with minimal re-definition of the defaults or
    overrides of user font settings. The body text and header styles are
    left alone except title, author and date classes are centered. A Pandoc TOC
    is not printed, URLs are printed after hyperlinks in parentheses.
    Block quotes are italicized. Tables are lightly styled with lines above
    and below the table and below the header with a boldface header. Code
    blocks are line wrapped.

    All elements that Pandoc and MultiMarkdown use should be listed here, even
    if the style is empty so you can easily add styling to anything.

    There are some elements in here for HTML5 output of Pandoc, but I have not
    gotten around to testing that yet.

/* NOTES:

    Stuff tried and failed:

    It seems that specifying font-family:serif in Safari will always use
    Times New Roman rather than the user's preferences setting.

    Making the font size different or a fixed value for print in case the screen
    font size is making the print font too big: Making font-size different for
    print than for screen causes horizontal lines to disappear in math when using
    MathJax under Safari.
