HTML Guide for projection

Bad value “screen,projection” for attribute “media” on element “link”: The media “projection” has been deprecated

deprecated

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.
