Wordpress - What are the standard admin CSS id/class tags?
We're working on updating http://dotorgstyleguide.wordpress.com/ to have more of this information and reflect the style updates from 3.2.
Other than that, I've seen a plugin (that I currently cannot locate) that shows a demo page of sorts that displays the various CSS selectors and what they look like, but I believe it was outdated. Other than that, your best option for now may be to just fire up Firebug/Web Inspector and take a look at wp-admin/css/wp-admin.dev.css.
Install this plugin and you see all elements, class and ids https://github.com/bueltge/WordPress-Admin-Style
*Note: For Frontend side - Here is the list which i have extracted after a lot of R&D in wordpress default css styles. I did my best to research everything and organize everything as accurately as possible. If you see anything missing or incomplete, please write in the comments. I hope it might help you to develop your desired plugins and themes *
