Skeletoni is based on the great Skeleton boilerplate. Skeletoni was created in 2025 mostly for industrial aplications which require fast development, readability, touch control, responsive layout and light/dark mode but not animations or fancy features.
Skeletoni CSS is single file with less than 1000 lines. For more complex but still simple alternative see Pico CSS.
Download skeletoni.css and test.html to see all it does. Below are some screenshots from test.html:
