HTML issues tagged as projection.
The projection
media type was deprecated in Media Queries 4.
Media types describe the general category of a device, for example screen
, print
and speech
.
CSS 2.1 and Media Queries 3 defined several additional media types (tty
, tv
, projection
, handheld
, braille
, embossed
, and aural
), but they were deprecated in Media Queries 4 and shouldn’t be used.
