Add URL Slugs as Body Classes

Add URL Slugs as Body Classes

Details
View on WordPress

This plug-in takes the URL, chops it into pieces, and adds each “piece” as an additional
class to the body tag.

Meaning, if your page’s URL is:
http://www.example.com/2012/02/24/wordpress-plugin-add-url-slugs-as-body-classes/
Your page’s body tag would have at least these classes:
2012 02 24 wordpress-plugin-add-url-slugs-as-body-classess

It gets much stronger when you start thinking about Categories or nested Pages:
http://www.example.com/category/wordpress/
which would add:
category wordpress
while:
http://www.example.com/movies/star-trek/wrath-of-khan/
would add:
movies star-trek wrath-of-khan

This allows you to very easily add custom CSS and/or JS to these pages based on these new CSS classes.

Please let me know if you have any questions/suggestions/thoughts,
