custom.css

/*
 This is my hacked up copy of Marked.app/Contents/Resources/gridless.css

 Changes:

 1. Smaller headings
 2. ~~No scrollbars~~ (I now prefer the Lion default behavior)
 3. Styling of definition lists ala LaTeX description lists.
 4. Centering h1.title, h3.author, h4.date (pandoc's title/author/date block).

 Gridless CSS, borrowed from the Gridless framework

 Original information from gridless.css:

 Main stylesheet: contains CSS normalization, base styles, typography with a vertical rhythm and some mobile-first media queries
 
 Credit is left where credit is due
 Much content and inspiration was taken from the normalize.css project: http://necolas.github.com/normalize.css/ and https://github.com/jonathantneal/normalize.css
