Water.css
A drop-in collection of CSS styles to make simple websites
...The stylesheet is intentionally small and dependency-free, making it a convenient drop-in for prototypes, documentation, and minimalist sites where heavy frameworks are overkill. It includes automatic dark and light themes and exposes CSS variables so you can adjust colors or spacing while keeping the overall aesthetic. Because it respects semantic HTML, it plays well with accessibility tools and reduces the risk of brittle component overrides. The result is a fast path to “good enough” styling that remains easy to customize when a project grows.
