Style action links

[jbickar]

D7 adds "action links" as a UX enhancement, which gets output as a ul.action-links. This renders by default with the same styling as any normal ul, but should have some styling implying action.

An example of this styling is the "add content" action link at admin/content when using the Seven admin theme.

An example of this is the "Clone" link that the Node Clone module creates. This shows up on the front-end theme when viewing a node (when logged in as a user that has permissions to clone nodes).
