- Changed: Make all color codes 3-char. Shave off a few bytes.
- Removed: all responsive layout besides the navigation links.
Everything else should work well at all window sizes without making
allowances for special cases.
- Removed: redundant CSS rules
- Added: centered images. Left-aligned images in a center-aligned column
of text break flow.
- Added: dark mode link colors for visited/active. Active link colors
give better a11y.
- Fix: don't show unnecessary scrollbar for <pre> blocks
Also put more comments in the source to explain why each rule is
important.
All this shrunk the CSS from 1065 bytes to 882 bytes (17% reduction)
- Text width was too wide on wide screens; reduce it.
- Make the nav-links' responsive layout for narrow viewports trigger at
a narrower window size. It used to trigger at 600px, but I made it
trigger at 32rem instead since the nav links aren't too wide. This
also handles cases where users' default sans-serif fonts are very
wide: rem measures by character width instead of pixels.
- Make the narrow-optimized multiline-navlinks the default, and make
widescreens a special case detected with a CSS media query.
Previously, widescreens were the default; however, this meant that
browsers that didn't support media queries (like dillo and netsurf)
couldn't switch to the multi-line navigation at narrow widths. This is
a good example of progressive enhancement; modern browsers will get
the same behavior as before, but the lowest common denominator will
see a better experience.
- Don't further reduce the max-width for narrow screens; narrow screens
are already narrow. We now have one less CSS rule.
