There is a live demo [0] with all the frameworks combined with some HTML5 boilerplate, and also a bookmarklet [1] that embeds the CSS switcher in any page (including web pages and local HTML files).
Those used to working with larger traditional frameworks may find it hard to see the point of minimal CSS frameworks. Igor Adamenko (of awsm.css) has a great and pithy explanation:
> Why? I have to create simple pages in my daily work. Sometimes it's compiled Markdown and sometimes it's pure HTML. I'd like to make them more beautiful without additional classes, ids, etc. So I did it.
These minimal CSS frameworks have also been surprisingly useful for converting Markdown files directly into PDFs [2]. Not all of them lend themselves to this purpose, obviously -- usually the simpler the theme the better.
Suggestions for any minimal frameworks that were missed are very welcome!
