Standard buttons
I use these for apps. Ancient and crude they may be, but they're simple.

Images

Hover over image for style. This will be used as the class
Yes, no/delete, add, change, abandon

I use this to replace a 'delete' button with a watchdog timer of say 5 seconds as a confirmation. The effect is that the user has to click again to confirm an action.

View details, go/visit/details, three styles of go back, external link
