   Examples

   
   is_tax();
   // When any custom taxonomy archive page is being displayed.
   
   is_tax( 'channel' );
   // When the archive page for taxonomy of 'channel' is being displayed.
   
   is_tax( 'channel', 'BBC1' );
   // When the archive page for taxonomy of 'channel' is being displayed
   // and the 'channel' taxonomy term is 'BBC1'.
   
   

Post Formats
The taxonomy slug for Post Formats differs from the Post Format slug. The register_taxonomy() function appends a post-format- base to the Post Format slug. So, e.g. while the “Aside” Post Format type has a slug of aside, the post_format taxonomy term “Aside” has a slug of post-format-aside.

// When the archive page for any Post Format term is being displayed.
is_tax( 'post_format' );

// When the archive page for Post Format type 'aside' is being displayed.
is_tax( 'post_format', 'post-format-aside' );
