The 9th April is CSS Naked Day. On this day many bloggers remove all styling from their blog. The idea is to promote awarenes of web standards. A well designed site, following web standards, will work well without any styling. A follow-on aim is to raise awareness of accessibility, since the plain, unstyled website will feel more how someone with a screen reader and other assistive technology will experience the site.
In preparation for this, have updated my theme picker to incldue a hard coded "Naked" CSS theme. If desired, this theme will be forced on CSS Naked Day, with no alternative for the end user.
