Learned about "#classless CSS frameworks" several days ago.
It's literally a single CSS file (or more if also using a preprocessor thingy).

current ideas for a new CSS style:::::
- stock appearance with marginal improvements from the opposite, like a tiny pinch of left padding that the "ground floor" style designed for early Neocities or awsm do
- 3 or 4-bit/teletext/CGA/ANSI/16 color scheme
- converting the plan 9 color scheme into a #theme
- Solarized Light but higher contrast
- honestly a high contrast "a11y" #theme that vaguely feels retro-ish
- absolutely no external fonts, system only
- XHTML 1.1 compliant
- still figuring out best way to add right side sidebar (yes i know about flexbox)
