Used to specify the content that should be generated for each matching result from a query. The action should be contained within a query or rule element.
One descendant of the action body should have a uri attribute set to the member variable. This element and its descendants may use variables in place of attribute values. Variables are a question mark followed by a name. For a matched rule, each variable will be a reference to data within the datasource, determined from the query. If the same variable appears multiple times, it will have the same value in each place.

Why does MDN look different?
MDN is changing to focus just on documenting web technologies. All the same great content is still here; we’re just changing some visual elements and navigation, to help you more quickly find the web technology docs you’re looking for.
But don’t worry, MDN and Mozilla are still together! In fact, we're updating MDN’s look to reflect Mozilla's new logo and colors.
