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.
Pico.css also has a class-light version, which is its main version.
These are frameworks that do not force you to apply their classes to many elements but require something like <div class="container"> or a bit of your own CSS for a page to look right. They may offer optional classes to style your content.
