 Monospace fonts are dear to many of us. 
-Some find them more readable, consistent, and beautiful, and than their proportional alternatives.
+Some find them more readable, consistent, and beautiful, than their proportional alternatives.
 Maybe we're just brainwashed from spending years in terminals?
 Or are we hopelessly nostalgic?

+On this page, I use a monospace grid to align text and draw diagrams.
+It's generated from a simple Markdown document (using Pandoc), and the CSS and a tiny bit of Javascript renders it on the grid.
+The page is responsive, shrinking in character-sized steps.
+Standard elements should _just work_, at least that's the goal.
+It's semantic HTML, rendered as if we were back in the 70s.
