/* CSS that adds the bare minimum for a simple layout */

/* This site's CSS does 11 major things:
 * 1. sans-serif instead of serif for low-res screens.
 * 2. Consistent font size; <pre> and <code> shouldn't be smaller than regular text.
 * 3. max text width for readability
 * 4. single-row nav links widescreen, multiline nav on narrow screens
 * 5. Bold "home" link that doubles as a site header
 * 6. Soft border around code in case it looks too similar to regular
 *    text, and to show it continue across more than one line
 * 7. Horizontally center inline images; left-aligned stick out.
 * 8. Padding fixes so the above changes don't make elements misalign.
 * 9. dark.css changes a few colors if the browser wants dark mode.
 * 10. Line height for consistent vertical rhythm
 * 11. Make blockquotes stand out a little; some browsers don't make them obvious
 * Everything else is browser defaults:
 * default fonts, non-dark-mode colors, etc.
