Media queries should be in em not rem

[lucadegasperi]

Since all media queries level one units are relative to the root element, setting the media queries in rems instead of ems, is useless and reduces the support for media queries in browsers like safari 5 (which do support rems but not in media queries)

[philwolstenholme]

Desktop Safari also has issues with rem in media queries. em are a safer choice: https://danburzo.ro/media-query-units/#the-trouble-with-safari-again-:~:text=The%20trouble%20with%20Safari%20(again)

Although there is https://www.npmjs.com/package/postcss-em-media-query which can be used alongside this plugin :)
