Changes

  • Removing deprecated device- prefix for media attribute features

Why

W3C Markup Validation throws errors on the application markup generated by this where appleStartup is true:

Error: Bad value (device-width: 320px) and (device-height: 480px) and (-webkit-device-pixel-ratio: 1) for attribute media on element link: Deprecated media feature device-width. For guidance, see the Deprecated Media Features section in the current Media Queries specification.

From line 2, column 19378; to line 2, column 19573

Fixes #273
Also fixes jantimon/favicons-webpack-plugin#98 further down the chain for the webpack plugin

Removing device- prefix as suggested here:
https://drafts.csswg.org/mediaqueries/#mf-deprecated

How

Done a find and replace in files to replace:
device-width with width
device-height with height

Feedback

This is also replacing a bunch of references in markdown files, which appears to be used for testing purposes.
I am not too familiar with testing like that, but, running npm run test does fail because the tests do not match the snapshots, please advise on how I can deal with that.
