Markdown Here Primary CSS Styling (I only changed it to use the PragmataPro Font)

markdown-here.css

/*
 * NOTE:
 * - The use of browser-specific styles (-moz-, -webkit-) should be avoided.
 *   If used, they may not render correctly for people reading the email in
 *   a different browser than the one from which the email was sent.
 * - The use of state-dependent styles (like a:hover) don't work because they
 *   don't match at the time the styles are made explicit. (In email, styles
 *   must be explicitly applied to all elements -- stylesheets get stripped.)

/* To add site specific rules, you can use the `data-md-url` attribute that we
   add to the wrapper element. Note that rules like this are used depending
   on the URL you're *sending* from, not the URL where the recipient views it.
