+ Name: navigation
+ Value: none | sequential | spatial
+ For: @media
+ Type: discrete
+
+
+ The 'navigation' media feature is used to query the user's ability navigate the page
+ and in particular to move the focus around
+ other than with a pointing device
+ (see the '@media/pointer' media feature).
+
+
+ - none

-
+ Indicates that there is no way for the user to directly navigate the focus.

+ Note: The user may still have the ability to interact with the page and activate
+ elements using a pointing mechanism
+ (see the '@media/pointer' media feature).

+
+ This media feature reflects the combined ability
+ of the User Agent and of the device it is running on.
+ If a User Agent would be able to support either spatial or sequential navigation,
+ but is running on a device which does not have an input mechanism capable of triggering them,
+ the corresponding query must not match.
+
+
+
+ For example, a TV browser operated solely through the D-pad on the remote control
+ would match
+ @media (navigation: spatial) { … },
+ but would not match
+ @media (navigation: sequential) { … }
+ nor
+ @media (pointer) { … }.
+
+ On the other hand,
+ a smartphone browser whose sole input mechanism is the touch screen
+ would match
+ @media (pointer) { … }
+ as well as
+ @media not (navigation) { … }.
