Classless CSS - click here for a wider page

This is a list of classless CSS themes and frameworks. "Classless" means a style sheet does not define special classes you must add to your HTML elements to style these elements. As a result, you can style any plain-HTML page just by linking to the style sheet. This is useful, for example, in prototyping.

You can sort these table columns by installing Tampermonkey in Firefox or chrome and then install Github sort content script

The columns are features I consider essential.

Dark column refers to automatic dark mode: prefers-color-scheme: dark

RT column refers to responsive typography, as a page gets smaller the size of the text should adjust, either dynamically or with breakpoints.

NSRO column refers to the css framework using normalize, sanitize, Reset, or Other(something similar).

KB column refers to the smallest minified css file with dark mode if available in kilobytes without gzip.

This table is sorted: Dark > RT > NSRO > KB (KB size is moot if the css framework does not include essential features, so I sort by it last.)

if a css framework has RT and NSRO but no dark mode, then I move those above frameworks that have dark mode but do not have RT or NSRO. (sorting according to which satisfys most of the features I consider essential)
