/**
 * Black compact & high contrast reveal.js theme, with headers not in capitals.
 *
 * By Peter Kehl. Based on black.(s)css by Hakim El Hattab, http://hakim.se
 *
 * - Keep the source similar to black.css - for easy comparison.
 * - $mainFontSize controls code blocks, too (although under some ratio).
