   and Media at Stuttgart Media University, Germany.


   His bachelor thesis builds upon the proposed media features by

   APA (see link above).


   Media feature candidates:


   prefers-color-scheme, prefers-reduced-motion, prefers-contrast,

   forced-colors, prefers-reduced-transparency,



   More from the GPII project: audio-description-enabled

   captions-enabled sign-language & sign-language-enabled

   pictograms-enabled self-voicing-enabled display-skiplinks

   table-of-contents session-timeout extended-session-timeout

   David: Is this intended for user agents or site owners?


   Niklas: UA have to implement the media queries. Site authors

   can write appropriate code.


   David: Is this already available in user agents?


   Niklas: Yes, but only with polyfills and a workaround for

   environment variables.


   David: This is good for the work of the personalization tf.

   <joconnor> Nice presentation 🙂


   <Fredrik> awe+


   David: Are there negative side effects of the hack?


   Niklas: In the draft for environment variables, there is a note

   that this is an open issue. But no negative side effects.


   <Fredrik> Great presentation, Niklas! Very interesting.
